Intensity of incident light

Vedclass · Answer

(A) According to the experimental observations of the photoelectric effect,the number of photoelectrons emitted per second is directly proportional to the intensity of the incident light,provided the frequency of the incident light is above the threshold frequency. Increasing the intensity means increasing the number of incident photons per unit area per unit time,which results in a higher number of photoelectrons being ejected from the metal surface.
