Who is watching for college practical 😂
Bro college name
Me😂
Thank you very much. Very useful, finally could complete college project
THANK YOU VERY MUCH SIR🙏
At 3:40 the a+b value should be (2.54x10^-2)/N, so please correct it.
You you watch 5-10 sec more you will get to know that my formula gives answer in centimeter and yours just give answer in metre. Both are correct infact.
Thank you for giving such a wonderful Chanel.. each video is very helpful in practical and also viva questions
Thanks dear
Thank you For best understanding video 👍👍 sir
@@RuchithaKallutla thanks for your words. For physics lecture you can visit my app GradXY on play store.
Best understanding video👏🙌
Good bhai❤❤
Sir kaash jitne easily aap experiment btate hai utne hi easily humse bhi exam me perform ho jate🥲
Ho jate h agr sab parameters alignments theek rakhi jaye to. Although video me ideal conditiona hoti h and hmara purpose hota h aapko process sikhana.
Are exam chodo normal lab me halat kharab ho jati he😂
Very nice ❤
Is refractive index gradient practical is available anywhere on RUclips???
@@Hit.870.99 you mean ref index of prism
@@AllLabExperiments noo it's topic is measurement of refractive index gradient by deflection of laser beam
I need it urgently
@@Hit.870.99 yes it is available. Search on this channel only. Or go to optics playlist.
Also download our app GradXY from google playstore for Physics Lectures...
@@Hit.870.99 may be it.is diff but.it must be related to prism. Just replace the light source from sodium lamp to laser...
Good 👍
Thank you
3:45 what will be for N = no of lines per mm
No this is lines per cm.
What is the line per inch of grating? Please
By definitions it is the no of slits available per inch. Its value is different for different gratings. Usually for the one shown in this the value is 15000 lines per inch.
How can we find the experimantal value to put it in the percentage error?
Wo know the standard value of wavelength of He Ne laser
