Question 152 of 200

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

Show answer and solution

Answer: (C) increases the number of photons incident and the K.E. of the ejected electrons remains unchanged.

The relation between the energy of photons and the intensity of photons is, hv=IAnhv=\dfrac{IA}{n}, where nn 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.
