oh yes.. you are right, I'm sorry. may i know what's the difference between the dispersion for photons and electrons? and the material is InGaAs.

May I know what is the difference between the dispersion relation for 100 and 001 on the E-K diagram? Can i say 001 has lesser dispersion? But why is it so?

I subsitute the values into F = qvB sin (theta)... I didnt sub two since those values are the same isn't it?

Hi! I have editted the attempt part. Do help solve the problem. Been pondering over it for sometime.

Homework Statement A proton moves in a horizontal plane with a velocity v. It is found that when there is a magnetic field of 10(power - 2)T (magnitude) pointing from west to east, the magnetic force on the proton has a magnitude of 3.2 x 10(power of -16)N and points downwards. It is also...
