I don't intend to give some hate on you, but the fact that you skipped application of TIR by saying that isko ek baar ncert se read krlena and not explaining the prism diagrams well in it is not appropriate than ex 9.6 one of the important question just by saying comments me btao saccha vidhyaarti aapne woh bhi last part skip kiya and u paused the video in between questions which is showing that u urself didn't knew the answers to it and u cross-checked this one might be a hunch but I hope u respect my opinion and sir u can do better and loved your style apart from these things !
If we don't pay then don't present any content on youtube instead of presenting less or wrong.......and who tells that we don't pay for it...... we pay by recharging our phone or wifi ...........
Sir at 1:57:07 se please ap iss Wale video mai prism sare re check kr sakte hai please. I'm not telling ye galat hai but mere confusion hai place points aor taken angles mai. Please sir agr ye correct hai tow bata de geye or disturbance k liye sorry❤ Sir quad. Aor traingle lete time 'Q' Kahan Gaya?
At 1:32:8 If I am not wrong, from the diagram the object distance is taken as negative then it means the equation no 1 becomes n¹/u + n²/v' = n²-n¹/r🤔 Plz reply sir I got confused there💫
Sir pls check the video at 31:31 you said that in triangle CMF but there is no point F .pls check sir its a humble request to you sir 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Ya fir sir aisa hai kya ki jab koi equation derive karte hai to sign convention nahi use karte lekin jab jo hame derivation se equation milti hai usme value rakhte samay bus sign convention use karte hai
Sir aapne prism ki derivation galat ki hai triangle PLR jaisa to kuch hai hi nhi isme ye teno point alag alag hai jo triangle ka formation nhi kar rhe@sachinsirphysics
Sir Esme refraction through a prism bilkul samajh nahi aaya aapne pura ulta fulta notation liya hai kuch samajh hi nahi aaya 😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😔😔😶😶😭😭😭😭😭😭😭
26:57 what sir said and what he is reading in comment Is criticism comment like some fool And selfish child Are doing But guru ji koi gal na Acc. To lenz law Jiski thali mai khata usi se virodh 😂😂😂 Love you sir keep smiling forever ❤❤❤🎉🎉

I would just say thanks a lot sir Like seriously this was the one I was searching for after so long etne lectures dekhne k bad best one shot Mila never commented on any video but you really deserve sir ❤ thanks sir ❤
43:01 sirrr aapne bola khood se karo mere answer aa raha h :- m=1.59 and v=15.90 aapke formula ke hi sab se , aur book ka answer dekh rahi hu toh usme -2.5 pata ni kaha se aa raha h 10*7.5/-2.5 is me 2.5 pata ni kaha se aa raha h 😭😭😭😭 please someone help
Sir I request you to please go through the older version of ncert because new one has deleted topics which causes problem in competitive exams for ncert revision
Someone- Physics kya h physics me , Jingoor se physics h , formula iske yadd hove na, samjh yu aave na Me - Physics pyaar hai apna 🤩 Sachin sir se padho pyar ho jayega physics se❣😎
Sir ap mentally bahut help karte hu ap ache se padhate bhi hu me apku judge nhi kar rhi bas yeh vinti h ki ap thoda formula and all ku thoda aur easy bana denge kiya mtlb thodi confusion hu jati h padhte padhte esloye baki thank u so much sir i hope yeh comments pake pass jaye rather then wrong views thank u❤
due to reflection.... when light rays fall on any surface they reflect and come to our eyes making things visible whereas in case where there is darkness we are not able to see the things because there is no light ray to reflect
sir refraction formula derive karte hue hamne phle se hi u and v with sign liye the then fir in questions hamne u and v ko dubara sign ke sath kyn liya ???
love u sir...my physics was the worst..but after watching these lecture..i have gained confidence that i can do better and love the way of your teaching☺☺
Every thing that our eye see is due to the reflected light from the object and when it goes into our cornea our eye acts as a receiver of light and makes the virtual of real image in our eye.
Hatss off to teacher like you sir MTLb school mai hamari teacher ne mirror equation ki derivation itni complex krayi thi sir ki kch smjh hi nhi aa rhi thi but after seeing ur veido sir it was totally easy than that aur sir asani se smjh bhi aa gya thank you sir ❤🙏🙏
Thank you so much sir Aapne sach me physics itna simply samjhaya ki lag hi nhi rha tha mai physics padh rahi hu Aur sir aap beech beech me thodi baate bhi kar rhe the jisse class aur interesting ban gyi THANK YOU SIR 😊
Sir , really thanks a lot sir Kitna bhi thanks bole kam h Aap sach me bahut acha padhate ho Shyd hi yt pe koi aur hooo❤❤ And sir board ka format aaise hi rakhiye acha lagta h Feel aata h ❤❤

Two things I like about him -
1st his derivations
2nd his glowing pen
21 February Wale attendance lagao 😂
Chemistry me organic nahi hori thi🙂
Physics me optics nahi hori🥲
Or maths me calculus nahi hogi🙂
Kya hoga mera..😭
try krte raho varna repeat hoga nothing much
Nice explanation sir 😊
but in 48:53 it's mentioned as a side view mirror which means the convex lens is not concave so the sign convention would differ
Yess and in ncert the ans is wrong...
@@Sonic_soul07 ncert is considered it as concave
@@Sonic_soul07ncert me wrong hai correct kardo
It's is concave mirror because 'f is + ve'
@@Dushyant-Bhargava no ncert think it is convex mirror
In refraction through prism( 2:02:11 ) shouldnt it be angle PLQ not PLR
Yes bro……
Divide it you will get
f=2.941×26.6
f=78.2
1:47:17
From where I can get the pdf of this lecture?
48:36 aap ne f ko (-1) bolla hai par jabb textbook ka solution dhek rhe hai tho vha pe (+1) diya hai
Sur please reply what to do ???
It’s +1 only because it’s the case of convex mirror
1:47:24 focal lenght of water is 78.125 cm
Mistake alert
Sir u teach amazing but in ( 2:02:00 ) refraction through a prism there is a mistake u took in a quadrilateral APQL BUT in derivation u took PLR as angle please make it correct sir
Btw I love ur videos plz make danbang series for Atoms nucleus semiconductor and dual naturae

Its 1:39 AM and I am starting this chapter for the first time as i don't study this chapter at school and Today is my exam
Wow wonder fulll btw kesa gaya exam???

small correction
It's triangle PLQ
Btw great explanation sir..❤
You right bro❤
it will be angle PLQ not PLR

Your question is right kuch bhe padha rahe hai
4 march ko physics ka paper h kis kis ne ab tyarri krni suru ki h like kre
Aaj khtm krdi is chapter k sath
😢
Apka he loda laganga abhi phy suru kar rha ho
2:07:43 sir idhar n1sin i =n2sin r1 hoga aapne n2sinr1 ki jagah n1sinr2 likha hei
I don't intend to give some hate on you, but the fact that you skipped application of TIR by saying that isko ek baar ncert se read krlena and not explaining the prism diagrams well in it is not appropriate than ex 9.6 one of the important question just by saying comments me btao saccha vidhyaarti aapne woh bhi last part skip kiya and u paused the video in between questions which is showing that u urself didn't knew the answers to it and u cross-checked this one might be a hunch but I hope u respect my opinion and sir u can do better and loved your style apart from these things !

Sir at 1:57:07 se please ap iss Wale video mai prism sare re check kr sakte hai please. I'm not telling ye galat hai but mere confusion hai place points aor taken angles mai. Please sir agr ye correct hai tow bata de geye or disturbance k liye sorry❤
Sir quad. Aor traingle lete time 'Q' Kahan Gaya?
It’s triangle PLQ not PLR

Btw thanks men!
Ex-9.7 (iii) ans-78.2cm......Thank you sir....🤩🤩
At 1:32:8
If I am not wrong, from the diagram the object distance is taken as negative then it means the equation no 1 becomes
n¹/u + n²/v' = n²-n¹/r🤔
Plz reply sir I got confused there💫
Bhai Mera bhi same question tha
Lekin ek bat yad rakhna derivation ke samay sign convention use na karna
Best video lecture for this chapter , sr aapki vibes bhot positive hai ,,, ❤❤❤
Sir pls check the video at 31:31 you said that in triangle CMF but there is no point F .pls check sir its a humble request to you sir 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
CMI hogana?
Sir is everything is covered in this vedio pls reply sir my syllabus is not completed
Sir example 9.4 me convex mirror hoga kyuki cars ke mirror toh convex hi hote h toh uski vgh se +39 lena chiye....
31:45 taken triangle CMF and angle is gama but please look at the diagram the triangle assumed is not the actual one
If the equation is correct than reflected ray should be pass through focus
Bro.. is your CBSE board?
Yes
@@yashparashar-le6ur umm can tell me which derivations are coming from this chapter?

5:14 sir kyuki light us painting pr ja kr vapis hmar eyes tk aati h toh hm us painting toh dekh skte hai otherwise nhi
Ya fir sir aisa hai kya ki jab koi equation derive karte hai to sign convention nahi use karte lekin jab jo hame derivation se equation milti hai usme value rakhte samay bus sign convention use karte hai
Sir aapne prism ki derivation galat ki hai triangle PLR jaisa to kuch hai hi nhi isme ye teno point alag alag hai jo triangle ka formation nhi kar rhe@sachinsirphysics

ye batch continue hoga na? wave optics ka new lecture acc to 2024 ayega? playlist me to chanakaneeti 4.0 dikha raha hai
SIR IS THE BEST TEACHER .....SIR 0.5 KI SPEED M PADHATE H ACCHA H 2X KRNE P DIKKAT NI HOTI
Such a peaceful voice which gives relief from physics problem👏👏🎉
One of the best explanations sir! Now I'm getting confidence to score more than 90% in the next exam...
Hi wo panda ko kya gift diya tha 😂🤣
acha 😂😂😂😂

Doubt- Why do we use Sin function only in Snell's law and not cos or tan? (i was asked this in my viva)
vaiiiiiiii aise sawal boards me nai ayenge behatar hai bhul jao

Previous student pls give honest reply, are these one shots enough to score 65+ in boards 12th????
Pls reply
43:01 sirrr aapne bola khood se karo mere answer aa raha h :- m=1.59 and v=15.90 aapke formula ke hi sab se , aur book ka answer dekh rahi hu toh usme -2.5 pata ni kaha se aa raha h 10*7.5/-2.5 is me 2.5 pata ni kaha se aa raha h 😭😭😭😭 please someone help
Sir I have a doubt...if n2/v-n1/u=n2-n1/R for spherical surfaces by lens then what is n/v-1/u=n-1/R..in our school we have taught this formula...??
First one is for rare to denser medium and 2nd one is for denser to rarer.

How the mirror equation derivation has triangle CMF and also gama as exterior angle
CMI hona chahiye
Jb light object pr pdkr hmari eyes me jati hai tab hme objects dikhai dete hai😊😊🥰🥰
Sirr.!! BRAMHASTRA SERIES.. es brr jan mai start kr dijiyega..plzz🤧🙏
Physics samjh ati nahi per apka video dekh kar achha laga😊😊
32:50 sir isme F ki bajaye I nahi aayega kyuki humne gamma angle I par liya hai from figure....

Light ray reflected from surface and gave sensesation in our eyes that's why we can visible anything
It's due to Electric field in EM wave
Sir me apki fan hu phle hmko physics nhi smjh aata tha bss apki vjh se physics mere sbse acha ho gya 😊
31:33 ∆cmf ki jagah ∆omM aayega
Sir I request you to please go through the older version of ncert because new one has deleted topics which causes problem in competitive exams for ncert revision
Sir mirror equation me last ki 3rd line me r=2f kasya aya plz tell me 34:52
Sir pahele physics kuch nahi samjh aata tha lekin jab se app mile ho na physics haalwa ho gaya hai mere liye thank you so much sir ❤❤❤❤
sir ji ma bhout weak student hu pls every q or example ko pua end tak karaya kiji means end tak answer tak pls pls sirrrrr
Sir aapne 2023-24 session k dual nature of radiation and matter aur atom vaale chapter ki video nhi bnaai n bnaadoo sirr please...☹️

due to reflection.... when light rays fall on any surface they reflect and come to our eyes making things visible whereas in case where there is darkness we are not able to see the things because there is no light ray to reflect

A very very very happy teacher's day sir 🎉🎉🎉🎉🎉🎉
love u sir...my physics was the worst..but after watching these lecture..i have gained confidence that i can do better and love the way of your teaching☺☺
Kya bro tum b ab ache score kr rhe ho or yeh series tumhare liye b helpful h
Every thing that our eye see is due to the reflected light from the object and when it goes into our cornea our eye acts as a receiver of light and makes the virtual of real image in our eye.
Notes milte hi nhi h telegram pe
You are the best physics teacher in this world 🌎🌍🎉🎉❤❤❤❤❤
Hatss off to teacher like you sir MTLb school mai hamari teacher ne mirror equation ki derivation itni complex krayi thi sir ki kch smjh hi nhi aa rhi thi but after seeing ur veido sir it was totally easy than that aur sir asani se smjh bhi aa gya thank you sir ❤🙏🙏
How you guys are preparing for derivations....i can't remember it for long time.
