The work function of caesium metal is 2.14 eV. When light of frequency 6 xx 10^14 Hz is incident on the metal surface, photomission of electrons occurs. What is the stopping potential.

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 .
