Important Question - Physics Class 12 [Electrons and Photons] . Q. What is threshold frequency? Ans. There is a certain minimum frequency of radiation below which there is no photoelectric emission where be the intensity of radiation. This minimum frequency is called threshold frequency. Different metals have different threshold frequencies. Illumination of a surface with light of frequency less than threshold frequency will not cause photoelectric emission. .
