Q. What is stopping voltage (or cut voltage)? Plot a graph of variation of photoelectric current with collector plate potential for two incident radiations of same frequency and different intensities.

Q. In a photoelectric experiment, intensity of a light source is doubled while its frequency is kept the same. Then consider the following statements.
(i) The saturation photocurrent remains almost the same.
(ii) The maximum kinetic energy of the photoelectrons is doubled.

Q. When monochromatic light of intensity

v = 3 v_{0}

v_{0}

is the threshold frequency) is incident on the cathode in a photoelectric experiment setup the saturation current is found to be

2 μ A

and the stopping potential is

V_{0}

. The photoelectric efficiency of the photo metal used to coat the cathode is independent of the frequency of incident radiation. If the Intensity of the incident radiation is doubled and its frequency halved then choose the correct statement(s).
