Problem
Answer the following giving reason :
a. All the photo electrons do not eject with the same kinetic energy when monochromatic light is incident on a metal surface.
b. The saturation current in case (a) is different for different intensity.
c. If one goes on increasing the wavelength of light incident on a metal surface, keeping its intensity constant, emission of photo electrons stop at a certain wavelength for this metal.
