Question
Assertion :Though light of a single frequency (monochromatic light) is incident on a metal, the energies of emitted photoelectrons are different. Reason: 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.

Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
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 which results in the ejected photo electrons with different energies despite of monochromatic incident radiation.
Hence Reason is the correct explanation of Assertion.
Option A is correct.
