Increase in the frequency of the incident radiations increases the

Light of intensity I and frequency v is incident on a photosenstive surface and causes photoelectric emission. What will be the effect on anode 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 remains the same. Explain, giving justification in each case.

An increase in the frequency of the incident light increase the velocity with which photoelectron is ejected. Explain how?

The threshold frequency of a metal is f_0 . When the light of frequency 2f_0 is incident on the metal plate, the maximum velocity of electrons emitted is v_1 . When the frequency of the incident radiation is increased to 5f_0 , the maximum velocity of electrons emitted is v_2 . Find the ratio of v_1 andv_2 .

Statement-1: Kinetic energy of photoelectrons increases with increases in the frequency of incident radiation Statement-2: The number of photoelectrons ejected increases with increases in intensity of incident radiation.

Light of intensity I and frequency v is incident on a photossensitive surface and causes photoelectric emission. Justify with the help of graph, the effect on photoelectric current when the frequency of incident radiation is increased all other factors remain the same.

The work function of a metal is 3.4 eV. If the frequency of incident radiation is increased to twice, then the work function of the metal becomes.
