Explain the term 'work function' of a metal. The threshold frequency of a metal is f0. When the light of frequency 2f0 is incident on the metal plate, the maximum velocity of electrons emitted is v1. When the frequency of the incident radiation is enhanced to 5f0, the maximum velocity of electrons emitted is v2. Find the ratio of v1 to v2.
