2. Statement:I Though light of a single frequency (monochromatic light) is incident on a 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

A

Explanation

Energy of photoelectrons emitted is different because after absorbing the photon, electrons within metals collide with other atoms before being ejected out of metal Hence, Statement II is correct explanation of Statement I.
