Question

When the light of frequency 2v0 (where v0 is

threshold frequency), is incident on a metal

plate, the maximum velocity of electrons emitted

is v1. When the frequency of the incident

radiation is increased to 5v0, the maximum

velocity of electrons emitted from the same plate

is v2. The ratio of v1 to v2 is

(2) 1 : 4

(3) 1 : 2

(4) 2 : 1
