Which of the following statements about the photoelectric effect, are true

Options

A. greater the frequency of the incident light, greater is the stopping potential.
B. greater the energy of photons is, the smaller is the stopping potential.
C. greater the intensity of light is, greater is the cut off frequency.
D. greater thefrequency of incident light is, greater is max kinetic energy of ejected electrons.

Answer

A, D

Explanation

`KE_(max)` and stopping potantial increase with increase in frequency and threshold frequency depends only on the metal.
