Question

In photoelectric effect when photons of energy h v fall on a photosensitive surface (work function h v0 ) electrons are emitted from the metallic surface. It is possible to say that (A) All ejected electrons have same kinetic energy equal to h v -h v 0 (B) The ejected electrons have a distribution of kinetic energy from zero to (h v-h v0) (C) The most energetic electrons have kinetic energy equal to h v (D) All ejected electrons have kinetic energy h v0

KE max =h v-h v0 and hence the energies of electrons can range anywhere between these values.

Q. In photoelectric effect when photons of energy $h v$ fall on a photosensitive surface (work function $h v_{0}$ ) electrons are emitted from the metallic surface. It is possible to say that

All ejected electrons have same kinetic energy equal to $h v - h v_{0}$

The ejected electrons have a distribution of kinetic energy from zero to $(h v - h v_{0})$

The most energetic electrons have kinetic energy equal to $h v$

All ejected electrons have kinetic energy $h v_{0}$

$K E_{m a x} = h v - h v_{0}$ and hence the energies of electrons can range anywhere between these values.

Q. In photoelectric effect when photons of energy hv fall on a photosensitive surface (work function hv0​ ) electrons are emitted from the metallic surface. It is possible to say that

All ejected electrons have same kinetic energy equal to hv−hv0​

The ejected electrons have a distribution of kinetic energy from zero to (hv−hv0​)

The most energetic electrons have kinetic energy equal to hv

All ejected electrons have kinetic energy hv0​
