1.	Assertion : Though light of a single frequency (monochromatic) is incident on a metal , the energies of emitted photoelectrons are different. Reason : The energy of electrons emitted from inside the metal surface is lost in collision with the other atoms in the metal.A. If both assertion and reason are true and reason is the correct explanation of assertion.B. If both assertion and reason are true but reason is not the correct explanation of assertion.C. If assertion is true but reason is false.D. If assertion and reason both are false.
Answer» Correct Answer - A When a light of single frequency falls on the electron of inner layer of metal , then this electron comes out of the metal , then this electron comes out of the metal surface a large number of collisions with atom of its upper layer.
