Question

Does the threshold frequency for a metal depend on the incident radiations?

Answer 1

Answer:

For a given metal, there exists a certain minimum frequency of incident radiation below which no photoelectrons are emitted. This frequency is called the threshold frequency. ... On the other hand, the stopping voltage does not depend on the intensity of the light (provided the light's frequency is kept fixed.)

Answer 2

Explanation:

no because threshold frequency is property which only depends on nature of surface of metal and can only be altered by applying suitable chemicals on metal surfaceand not on intensity of light .
