Problem

Threshold frequency of metal is f0f_0. When light of frequency 2f02 f_0 is incident on metal plate, maximum velocity of electron emitted is v1v_1. When frequency of incident radiation is increased to 5f05 f_0, maximum velocity of electrons emitted is v2v_2. Find the ratio of v1v_1 to v2v_2.
