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

Options

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 `(h v - hv _(0))`
C. the most energetic electrons have kinetic energy equal to hv
D. all ejected electrons have kinetic energy `hv_(0)`

Answer

B
