Q. Statement- 1: The kinetic energy of photoelectrons increases with increase in frequency of incident light.

Statement- 2: The number of photoelectrons ejected increases with increase in intensity of light.

Q. Assertion :The kinetic energy of the photoelectron ejected increases with increase in intensity of incident light. Reason: Increase in intensity of incident light increases the rate of emission.

Q. Explain giving reasons for the following :
(a) Photoelectric current in a photocell increases with the increase in the intensity of the incident radiation.
(b) The stopping potential

(V_{0})

varies linearly with the frequency (

ν

) of the incident radiation for a given photosensitive surface with the slope remaining the same for different surfaces.
(c) Maximum kinetic energy of the photoelectrons is independent of the intensity of incident radiation.

Q. (A) The kinetic energy of the photoelectron ejected increases with increase in the intensity of incident radiation.
(R) Increase in intensity of incident light increases the rate of emission.

Q. When light of frequency

v_{1}

is incident on a metal with work function

W

h v_{1} > W)

, the photocurrent falls to zero at a stopping potential of

V_{1}

. If the frequency of light is increased to

v_{2}

, the stopping potential changes to

V_{2}

. Therefore, the charge of an electron is given by
