Har saal Feb kei month mei practical sei ek din pahle bacchei yahan aate hai and I am one of them. Are you too ? And seriously this channel is the best Thanks a lot!!!!!!!! ( use headphones)
your perfection is not only good & better but best..... your video is very helpful me to take interest in physics practical ..after sawing your video there was increase in my knowledge...thanks...sir...
a beautiful lab, well maintained apparatus, sir in coat suit , nice explanation even about the errors is something our schools can never achieve! thanks a lot to this channel
Sir radius of curvature of lens is 20 so focal length will be 10 by spherometer. But when you are measuring focal length by measuring x1 then it is 20 CM for same lens.. How this much variation possible... Please clear this doubt.. Thanks.
Very good video,, but I have one doubt after measuring by spherometer the radius of curvature is 20.03 and in experimental data the focal length of lens is 19. Something,,, how's that possible sir
This man saved the lives of so many students
There's no sound
what does it mean
what does it mean ?
@@arunavaadhikari8179 Use headphone.
Fact
one minute of silence for those who are watching this video 10 hours before the practicle exam
🙋

One min of silence for people who still write this bs......☝️

well i am watching it 1/2 hour before exams and alas this came

Thank you Edu
I'm so i'm so grateful to edu
Present here
Tum sab fool ho f2=59.95 cm which is wrong It is -59.95cm
True 👍🏻
No this time in April
we are told that we just need to memorize everything (even the readings) and just act before the examiner that we are taking the readings
Ramit Monga lol your school is a scam
Really😂😂
🤦🏾
That's my principle for most of the optics experiments. Not school sponsored just students creativity.
Same here😋
seriously ..sir..the way you taught all these practicals helped me a lot..
2020 boards gang gang 🗿
Where are my-
"practical se ek raat phle vedio dekhne wali gang"??
Because of this man my physics journal is complete
your perfection is not only good & better but best..... your video is very helpful me to take interest in physics practical ..after sawing your video there was increase in my knowledge...thanks...sir...
Note :~ Kindly Use Headphone to hear the sound .. it is a special type of video , Without headphones you cannot hear
😂😂
I am in my practical lab.
I sneaked in the phone.
The practical examiner is watching me
Really helpful thanks !!!!!
LIFE SAVOUR!!
You were giving your practicals in evening?
Its 21:57 and you commented 43 minutes ago.
@@mohanjha9593 Why, yes I was 😂😂
@@friendsfurrever3221 What ??!! where in the country you were giving your practicals in night😬😂
@@mohanjha9593 Texas
@@friendsfurrever3221 I see why now.
a beautiful lab, well maintained apparatus, sir in coat suit , nice explanation even about the errors is something our schools can never achieve! thanks a lot to this channel
Sir you literally saved the practical exams of so many students. God bless you sir 🙏🙏🔥
This video is underrated. 👏
i watched the whole video without sound untill i came to frm the comments that using headphones u are able to hear the sound😣😣
Sir please give some audio..... only we are hearing music....please enhance the audio quality.
Practical in 1 hr . Watching this in school
Tomorrow my practical ...and I am seeing this experiment for the first time ...... legend is born 😎
Less than 10 hours for practical exam
Me: hey !! The intro music is BTS euphoria
Legit me rn 😂
how did ur prcticls go
No this intro music is not from BTS euphoria cause euphoria is a new song while this video is like 5 years ago
If that ain't me, sis-
@@blahblahshutup6024 actually I am a boy this is my mum's account
I AM VERY HAPPY BECAUSE OF UR EDU NOVUS THANKS A LOT SIR !!!!!!!!
Good video. Helped a lot. But one suggestion.... Remove the music and make sure that the sir's voice is more audible.
USE HEADPHONES.
Thanks! tomorrow ispractical exam and the right video at right time.
Thank you Edu
Thank you Edu
Thank you Edu
I'm so i'm so grateful to edu
I like sir voice .....so soothing 😌
so nice sir, today is my physics practical n I done well..
6.19 am board exam 9.00am....
Me:thuglife*
you really saved my practicals,bro!!! THANKS A LOT!!!
Is it mandatory that the difference between F1 and F is 10 cm...
I am in doubt ...plz reply
2019 practicals anyone ??😂
Mine..... tomorrow
@@abhishekrao9232 Mine too
Please send me some solved graph otherwise I am done :(
Mine 4 feb
Mine tomorrow 😆🤣
It is very use full to science student. Thank you sir.
Watching before two hours of exam!
Tomorrow my practical exam
Me still don't know what is battery eliminator
Bro how did it go? I also don't know the meaning of battery eliminator, did u get to know what it is lol?
My practical is on 31 and now I am gonna watch a good movie 😂😂😂any suggestion
@@nishikaverma67 lol are u serious bro? 🤣🤣
Try watching ohm's law experiment class 12 by R kK Tomar. Its really helpful 😀😁

How about potc??
My favorite 😍
Sir object needle coincides with its image one when it is kept at centre of curvature. So what we are measuring is radius of curvature. Isn't it so??
I've never seen a TH-cam video so loud and clear!! (👈sarcasm by the way)
use earphone
anirudha chari worst sarcasm ever
bhava headphone use kar
@@hemiacetal1331 seems like before commenting he searched for the meaning of sarcasm😂
do we have to find radius of curvature by spherometer
Amazing explanation clear voice ✅✅
6 hours left for practical exam 😂😂😂
DISCLAIMER: Use your headphones for the audio.
Well thank me later!👍
ffccukk man. u just saved my 30 marks. thank you now.!
Why is the point where the object needle and its image coinciding, the focus and not twice the focus?
Best of luck for your tomorrow practical 🙃
thank you
Your channel is a legend!
which type of convex lens is used in this experiment? plano, double or biconvex lens?
thank u sir for your wonderful teaching
Great video. ...Thanks a ton 😄😄
2020 practicals anyone?
nice explanations thnkz a lot
Thank you sir.. For helping us I don't have any thins go give u but I really thank u.. It helps a lot
If focal length of lens without water 19.9 then how could it be radius 20 ????
very helpful for practical exams
Tomorrow is my physics practical ....🙏🙏🙏
great video,use headphones for sound
Wow such a very nice explanation ❤️❤️
guys hes my physics sir:)
It is very sucessfully practical for understanding the students
thank u, this is very good job for students
Thanks sir this is so much better for me
I am watching it in school before experiment. 😁
But where we use spherometer and how
Sir please also include spherometer.i don't know how to find it ....
voice and concept both are very clear
ALOK RANJAN lmao
great video sir...👏👏
doing a great job . thank you
nice...... video....sir......
Thank you very much sir you help me a lot for practical s .
But how to find radius of curvature using spherometer?
Will understand easily
use headphone or lead for sound
How we find radius of curvature ?
f2 is negative value ie -59.94 but why should taken +59.94 ,please explain
Please sir... Can you make electronics experiment videos .. Please.. Its a humble request
Sir radius of curvature of lens is 20 so focal length will be 10 by spherometer. But when you are measuring focal length by measuring x1 then it is 20 CM for same lens.. How this much variation possible... Please clear this doubt.. Thanks.
Sir,we are considering value for R=2.5cm. we get the answer for refractive index of liquid =0.96.Is it correct.....
We can hear his voice only while using headphones. What sorcery is this??
This channel is awesome!
How to find refractive index of convex lens without using spherometer?
Abhijith Muralidharan you can't
nope
you can but that won't be that accurate. find the focal length(with other expts) and then apply lens maker's formula
thank you edunovus…...I trusted you and I made it...
Thank u very much sir these videos helped me a lot
Covid batch, Hello.
Heyyo
hi
Good video
Very good video,, but I have one doubt after measuring by spherometer the radius of curvature is 20.03 and in experimental data the focal length of lens is 19. Something,,, how's that possible sir
Can someone clarify me how can we take 3 reading of this experiment as perfect reading is always one ????
U r a life saver.ty
Sir the value of f2 is coming negative according to your formula
Thank you sir for this amazing video
These videos are saviours.
It's really awesome
rough focal length of the convex lens =10 cm and calculated focal length of convex lens = 19.95cm what's this.....
same confusion!.. please reply if you got the answer for this
sure sir..
@@chandni1453 I'm also a class 12th student so don't call me sir please 😂. Thank you
Great video Sir
Ok but didn't u get negative value of f2??
Just perfect for any cbse student
Good practicals
Sir,you have not considered the sign conventions while calculating it.Should have been considered!
Sabuj Dutta no..not needed
Efforts made for usshould be appreciated
Great video
Can you please fix the sound ?
Why can't people at the corner of a class not see the black board clearly but those in the centre can?
6:05
2021 practicals anyone??😅😅
very good explanation
Use your headphones to hear the audio properly!
Yeah this is the only drawback
good video ,very helpful
