If lamda_o and lamda be the threshold wavelength and wavelength of incident light , the velocity of photoelectron ejected from the metal surface is :

If lamda_o and lamda be the threshold wavelength and wavelength of incident light , the velocity of photoelectron ejected from the metal surface is :

If lamda_o and lamda be the threshold wavelength and wavelength of incident light , the velocity of photoelectron ejected from the metal surface is :

Assertion : The number of electrons ejected from a metal surface depend upon the frequency of light. Reason : There is a time lag between the striking of light beam and the ejection of electrons from the metal surface.

Assertion : The number of electrons ejected from a metal surface depend upon the frequency of light. Reason : There is a time lag between the striking of light beam and the ejection of electrons from the metal surface.

Assertion : Kinetic energy of photo electrons emitted by a photosensitive surface depends upon the intensity of incident photon. Reason : The ejection of electrons from metallic surface is possible with frequency of incident photon below the threshold frequency.
