I think u have to use the Electron Diffraction experiment.

What is that? No idea about it.
I dont know what is concentric rings and stuffs, never studied about it.

Can I get notes on Hall effect/Hall probe thingy (A2 level)?
Thank you.

Thanks a lottttttttttt!! ^_^
Do u have more notes???
This concetric ring I never found in my text book. From where did u get?

Can I get notes on hall probe?

How De broglie wavlength and radius is related?

 

[princess Anu]

Crms is proportional to sqrt(T)
Crms1/Crms2 = sqrt(T1)/sqrt(T2)
500/1000 = sqrt(300)/sqrt(T2)
T2 = 1200K

Thanks
But which formula are you using
Where does it say crms sqrt is proportional to t sqrt

Thanks
But which formula are you using
Where does it say crms sqrt is proportional to t sqrt

Crms = sqrt(3kT/m)
This formula when m is constant Crms is prop. sqrt T

Question 15. I need the working

I gotta know that 2 * pi * r = n * lambda (lambda prop. r)
IDK how this comes from

Only this will be helpful?
I have seen questions like why voltage is maximum when probe is parallel to magnetic field and stuff..
Thanks..

Does anyone has any notes on doppler effect
Do we have to do it for A2?
