Does the stopping potential in photoelectric emissiondepend upon
the frequency of the incident radiation?

Define stopping potential.

According to Einstein's photoelectric equation, the graph between kinetic energy of photoelectrons ejected and the frequency of the incident radiation is :

Is photoelectric emission possible at all frequencies?

Define threshold frequency for photoelectric emission.

Given instructions same as in chapter 1. Assertion: For photoelectric effect to take place, the frequency of incident of incident radiations should be more than threshold frequency of a given metal Reason: 1/2 mv^2=h(v-v_0) .

Write Einstein's photoelectrical equation in terms of the stopping potential and the threshold frequency for a given photosensitive material. Draw a plot showing the variation of stopping potential vs the frequency of incident radiation.

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 .
