The kinetic energy of photo electrons depends on (A) Frequency of incident radiation (B) Velocity of incident radiation (C) Intensity of incident radiation (D) Wavelength of incident radiation

When light of sufficiently high frequency is incident on a metallic surface, electrons are emitted from the metallic surface. This phenomenon is called photoelectric emission. Kinetic energy of the emitted photoelectrons depends on the wavelength of incident light and is independent of the intensity of light. Number of emitted photoelectrons depends on intensity.
