Question

the threshold frequency of a metal is f when the light frequency 2f is incident on the metal plate the maximum velocity of photoelectrons is v2. The ratio of v1:v2​

Answer 1

Answer:

Explanation:The threshold frequency of a metal is f0. When the light of frequency 2f0 is incident on the metal plate, the maximum velocity of electron emitted is v1. When the frequency of the incident radiation is increased to 5f0, the maximum velocity of electrons emitted is v2.
