Explain the term work function of a metal, Physics

Assignment Help:

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 v₁to v₂.
