THANKS from Canada! I was looking for a well illustrated explaination like this one for my students!
🤓🙏
@@AllLabExperimentssir thanks from USA , i am completing my PhD program in london University, nobody came to teach me this simple way of taking reading on the scale of spectrometer, you made my day.❤❤❤❤
@@freefiregamingzone9022 🤓👍
As an instructor, how did you learn back then?
Great one
Now it's very usefull for take readings...👍
Nicely represented
Hello guys! Thank You very much for watching this video. Please give me suggestions about my future videos... :-)

Such a nice and great explanation. Lots of thanks to you sir 🙏🙏🙏.
Thank you bro ,really helpful video ❤️✊🏻 my doctor made this simple measurement kinda impossible to calculate.
Good job
Very nice keep it up
Wonderful Explanation Sachin Sir..
Nice video. Very helpful for pupils preparing for exams. Go on... Best wishes
A life saver for students ❤🙌
Thank you sir🙏, now I understood
Very supportive video thanks sir
Thank you sir.very good explanation.
Thankyou so much for such a greatful explanation sir 🙏🏻🙏🏻
It helped me a lot, thanks and gratitude.
This is very helpful..🙌🙌
very easy explanation 👌
brilliant work 🎖🎖🎖
Nice
Great explanation
Best explanation ❤️
Excellent explanation!!
Thank u sir explaining is good I understand ✨🙏
Such a super and well understandable explanation sir. Thank you soo much. I really appreciate ur efforts sir🎉😊
Finally it makes sense!! Thanks!
You explained nicely ❤️in simple way😘😘
This vedio is really helpful😄🙏
Nice bro 👍, this really helps me a lot..
Great explanation ❣️
Excellent explanation tqsm sir keep uploading more videos so that we can hv more knowledge...
Very good explanation 😀
Great video and clear explanation, thank you.
Very nice explanation ☺☺
I am from India, and it was most important video for me..❤
Thank you so much sir..
Tq sir superb explanation
short and perfect
Really very helpful video sir 👍
Superb video sir !!!
Tq so much sir
Very good sir
Thank you so much sir
Thank you, now this exp is clear to me ✨
Thankyou verymuch sir🙏🙏🙏🙏🙏🙏
Thanks bro... You save my life 🙏🙏
Really very good video to understand the spectrometer reading, very neatly explained.thank you
n
.
Its helped me lot sir thankyou.... ☺️🤗
best🥰
Wow very nice one tqsm
very nice sir🙏
Thank you so much sir🙏
Thank you sir🙏🙏
Thank you bro it's so helpful for me
thank you so much sir ............bada confusion tha aab sab clear ho gya thanks
Thanks a lot 👍👍❤❤
👌👌👌👌👌
Finally find a video from whr i can clearly understood the experiment _! Thankyou ❤️
My pleasure Paridhi...
Thanks from America 😅
Thanks a lot.
Thanks sir
Thanks
Thanks you very much
Thank you so much sir☺☺
Thank u sir. 🙏💐
Thnky so much❤❤❤
Very very useful 👌
Thanks Jagadeesh...
Thanx✌
Thanks alot
But I think instead of using Least count of the system ,we use the least count of the vernier scale which is nearly 30 minutes (exactly 29 minutes) or 0.5° 🙏🤔🤔
No
Littlerally wasted 2-3 hours in college understanding it. Thanks !!
A similar situation of a very good student inspired me to make this channel. Hope it is serving its purpose.
Wow
I am in sri lanka 🇱🇰
Thank you sir 🙏🙏🙏🙏
My pleasure
Your way of explaining is very good
Thanks
Thank you Sachin
Thanks Cormac 😊🙏
👍
Sir you r great.....🙂
Ha ha... I am not great dear but science is great... and m just following a better track to teach you that science...
@@AllLabExperiments your way is great that's why we follows you .
All the concepts are tough in very simple terms.
@@meghasharma7075 These are infact very simple. Your teachers make it difficult... The only thing you need is clarity over the cocepts.... I am preparing a series of short lectures for you guys. have launched two videos of it - why differentiation of sin x is cos x and why there are 3 equations of moiton. ==> ""just check them and support by sharing."" you will say that these are really very very easy topics. Now i am preparing a video on why you see a lot of exp(x) in physics. Which will surely change your mind in a certain way that many topics in science you thought different are infact the same and very easy to digest...
Good explanation 👏👏
Sir please upload characteristics of thermistor experiment in detail... 🙏
Electronics wale experiments abhi kuch din baad cover honge
Please upload a video of the calculation.
Please upload a video of the calculation.
Please upload a video with least count.
Thanks 👍👍👍😊
sir is it always necessary to take an vernier scale reading if 0 of the vernier scale is precisely coinciding with the main scale then also we have to apply the formula to calculate the final reading...
Just take vernier scale reading to be zero and make the table accordingly. Although formula will also give the reading same as the main scale reading but for the sake of making ur observation table, do it.
Can u please upload working principle of spectrometer
Watch my video on how to read Vernier Caliper. It is in Hindi but with english subtitles. You will get to know how such systems work
Least count another simple formula has L.C=one M.S.R÷total number of vernier scale divisions.
Can you explain me because I am unable to understand it pls help me I have project to do
@@yashumale7969 one M S R =1/2 °(1/2×60)
Total vernier divisions =30
LC =one MSR ÷ TVD
LC= (1/2×60)÷30
LC=1
Sir how to calculate smallest division on main scale
Just look at the main scale... Choose an interval like between 260 and 265 degree marks there are 10 divisions then each division is half of a degree.
@@AllLabExperiments i have to calculate LC of spectrometer and formula for that is =smallest division on main scale /total number of division on vernier scale.
But i got wrong answer so if you tell me right answer it is helpful for me 🙏.
@@addictionforphysics8509 check out the formula narrated by me in this video.
Why the de main scale here is changing from 291 to 294.5 2:41
Its not changing. Vernier scale covers this region on main scale. That is 14.5 degree.
Sir can u make a video on speed of sound by kundt's tube?
Can you send me its full details but presently i am buzy with preparing my website containing free study material for students. But i can add this to my future projects.
@@AllLabExperiments sir in this tube we measure loops formed by lycopodium powder upon providing frequency
Sure jb apko time mily ap video bna dijyay ga maery finalz sy pehly ...it will be huge favour
how do you calculate the reading error of the spectrometer?
If the vernier scale is not in touch with the main scale... Then there a scope of random eroor otherwise your least count is the maximum error in a scale,s reading...
@@AllLabExperiments i have one doubt. How to know which is v1 vernier scale 1 and vernier scale 2 please sir reply
Sir how can we find that angle is in point ,as u find that angle is 278°30 min but how can we know angle in min ,pls reply me sir 🙏
One degree is 60 min. As there is a mark of half degree (0.5 degree) therefore, it starts from 30 min in advance.
@@AllLabExperiments sir mere khne ka mtlb ye tha ki jb 280 ke aas paas ka angle hai toh hmko kaise pta ki 278 point something hi hoga ye 278 kaise maan liye hum log
Thankyou but for vsr ony the method is 1/60 means vc lestcount /60
It is when your least count is 1 minute it means 1/60 degree. For different scales it may vary.
Please help me to understood least count..I couldn't get it 🙏
Watch my video on vernier caliper. You will surely get it.
How did that 278° 30' came i am confused on 30'
Because the small mark after 278 has also been crossed by the zero of vernier scale
@@AllLabExperiments thank you so much sir for the explanation ❣️
id really like to leave a like but i can't ruin it
Its okay. Its upto you...

how dyou calculate the error
Its hard to measure unless you know the absolute value of anything you are going to measure
@@AllLabExperiments like in this experiment we did, we were measuring the angles at which certain colours of the spectrum are seen. We had to inculde the uncertainty in our measurements.?
Or you can repeate a measurement and find its standard deviation.
@@AllLabExperiments oh okay thanks
There are only two options for vidio quality
I don't know that is You tube's internal matter I guess...
Tamil bro
Sorry but dont know tamil. If somebody can do a voiceover then i can make one.
Malayalam video nokki nadakkunna ngan
I Didnt get you
Good job
Nice
