Answer is:
does not depend on photon frequency but only on intensity of incident
Explanation:
in photoelectric effect, the photoelectric current does not depend on photon frequency but only on intensity of incident
Answer is:
angular momentum
Explanation:
If we consider electrons and photons of the same wavelength, then they will have the same angular momentum
