Question

Light of intensity i' and frequency ' is incident on a photosensitive surface and causes photoelectric emission. What will be the effect onanode current when (i) the intensity of light is gradually increased, (ii) the frequency of incident radiation is increased, and (iii) the anode potential is increased? In each case, all other factors remain the same.Explain, giving justification in each case.

Answer 1

Explanation:

Keeping the anode potential and the frequency of the incident radiation constant, if the intensity of the incident light is increased, the photoelectric current or the anode current increases linearly. ... Hence, with the increase in the frequency of incident radiation, there will not be any change in the anode current
