Question

Photoelectric emission is observed from a metallic surface for frequencies v1 and v2 of the incident light rays (v1>v2). If the maximum values of kinetic energy of photoelectrons emitted in the two cases are in the ratio of 1:K, then the threshold frequency of the metallic surface is: 1. V1-v2/K-1 2. Kv1-v2/K-1 3. Kv2-v1/k-1 4. V2-v1/k-1 Give the solution also
