In photoelectric effect, the electrons are ejected from metals if the incident light has a certain minimum

wavelength

frequency

amplitude

angle of incidence

Solution

frequency

In photoelectric effect for a given photosensitive material, there exists a certain minimum cut-off frequency, called the threshold frequency, below which no emission of photoelectrons takes place no matter how intense the light is.
