In a photoelectric experiment, increasing the intensity of incident light:

Options

Aincreases the number of photons incident and also increases the K.E. of the ejected electrons.
Bincreases the frequency of photons incident and increases the K.E. of the ejected electrons.
Cincreases the number of photons incident and the K.E. of the ejected electrons remains unchanged.
Dincreases the frequency of photons incident and the K.E. of the ejected electrons remains unchanged.

Correct answer

C. increases the number of photons incident and the K.E. of the ejected electrons remains unchanged.

Step-by-step solution

The relation between the energy of photons and the intensity of photons is,

hv = \dfrac{IA}{n}

, where

n

is the number of photons, if we increase the number of photons then frequency does not change it means total energy and kinetic energy of photon remains unchanged but due to to this property the intensity of light is increased.
