STATEMENT - 1: When ultraviolet light is incident on a photocell, its stopping potential is V0 and the maximum kinetic energy of the photoelectrons is Kmax. When the ultraviolet light is replaced by X-rays, both V0 and Kmax increase.
STATEMENT - 2: Photoelectrons are emitted with speeds ranging from zero to a maximum value because of the range of frequencies present in the incident light.
In the light of the above statements, choose the correct answer from the options given below:
- Statement - 1 is True, Statement - 2 is True; Statement - 2 is a correct explanation for Statement - 1
- Statement - 1 is True, Statement - 2 is True; Statement - 2 is NOT a correct explanation for Statement - 1
