Question

What happens if the frequency of incident radiation is below the threshold frequency?

विकल्प

• The stopping potential increases with light intensity

• Photoelectrons are emitted whenever intensity increases

• No photoelectric emission occurs, however strong the light may be

• All emitted electrons are collected in the saturation region

Answer 1

Below the threshold frequency, no photoelectric emission occurs. Increasing the strength of the light does not overcome this frequency requirement.
