An increase in frequency of incident light increases the velocity with which a photoelectron is ejhected .Explain.

What is the effect of decrease in wavelength of incident light on the velocity of photoelectrons?

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 .

If lamda_o and lamda be the threshold wavelength and wavelength of incident light , the velocity of photoelectron ejected from the metal surface is :

Define the term work function of a metal. 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 and v_2 .

STATEMENT-1: The kinetic energy of photo-electrons increases with increase in frequency of incident light were vgtv_(o). STATEMENT-2: Whenever intenksity of light is increased the number of photo-electron ejected always increases.
