In each of the following questions, a statement is given and a corresponding statement or reason is given just below it. In the statement, mark the correct answer as
Statement-I: Though light of a single frequency (monochromic light) is incident ona metal, the energies of emitted photoelectrons are different
Statement-II: The energy of electrons just after they absorb photons incident on the metal surface may be lost in collision with other atoms in the metal before the electron is ejected out of the metal.

Answer

B

Explanation

Even through all the electrons absorb the same amount of energy , as difference electrons may come from different depths from the surface they may lose different amount of energy in collisions with other atoms while coming on to the surface hence the emitted photo electrons have different kinetic energies.
