Photons of frequency, v, fall on metal surface for which the threshold frequency is `v_(0)`. Then

Options

A. All ejected electrons have the same kinetic energy, `h(v-v_(0))`.
B. The ejected electrons have a distribution of kinetic energy from zero to `h(v-v_(0))`.
C. The most energetic electron has kinetic energy hv.
D. The average kinetic energy of ejected electrons is `h(v-v_(0))`.

Answer

B

Explanation

Due to distribution of kinetic energy of ejected photoelectrons inside the crystal.
