Vedclass · Answer

(B) According to the photoelectric effect,the number of photoelectrons emitted per unit time is directly proportional to the number of incident photons per unit time.Since the intensity of light $(I)$ is defined as the energy incident per unit area per unit time,and for a given frequency,the energy of each photon is constant $(E = hv)$,the intensity is directly proportional to the number of incident photons.Therefore,the number of photoelectrons emitted is directly proportional to the intensity of the incident light $(I)$,provided the frequency $v$ is greater than the threshold frequency $v_0$.

The number of photoelectrons emitted for light of frequency $v$ (higher than the threshold frequency $v_0$) is proportional to
