Question

light at a place is given as E = Eo sin (wt) which falls on a
metal surface having work function W calculate the max K E of a
photoelectron

Somnath physics · Accepted Answer

Now KE of a photoelectron depends upon the
waves frequency Î½

Ï‰ =
2Ï€Î½

=> Î½ =
Ï‰/2Ï€

Again,

h Î½ = W + KE

=> KE = h Î½
â€“ W

=> KE = hÏ‰/2Ï€ -
W

light at a place is given as E = Eo sin (wt) which falls on a metal surface having work function W. calculate the max. K.E. of a photoelectron.
