In a photoelectric effect, electrons are emitted

If I_(0) is the threshold wavelength for photoelectric emission, 1 the wavelength of light falling on the surface of a metal and m is the mass of the electron, then the velocity of ejected electron is given by

Assertion : In photoelectron emission the velocity of electron ejected from near the surface is larger than that coming from interior of metal. Reaon : The velocity of ejected electron will be zero.
