Why does the maximum velocity of photo-electron not depend upon the inetensity of radiation ?Explain.

In photoelectric effect, does the photoelectric current depend on the intensity of incident radiation? Give reasons.

Define the term work function of a metal. The threshold frequency of a metal is 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 of 5f_0 the maximum velocity of electrons emitted is v_2 . Find the ratio of v_1 to v_2 .

The work done on a object does not depend upon the

Cell potential of the cell does not depend upon
