Question

Help~, when different colored incident light shines on a metal cathode, photo electrons jumps off the metal cathode with different speed.

Can someone tell me how different colored incident light affects the speed of the photo electrons?

My assumption is that I thought the speed of light is constant 3x10^8 m/s and I know that different colored light will have different wavelength thus different frequency

Answer 2

\[e=h \nu \]
more will be the (nu)frequency more will be energy

Answer 3

also, e=1/2m(v)^2 more will be energy more will be speed of electron
