Threshold Frequency, Threshold Wavelength, Work Function and Stopping Potential

1)Threshold Frequency Threshold frequency is the minimum frequency of incident radiation on the metal surface below which photoelectrons emitted from the surface.It’s value is fixed for fixed metal surface but varies from one to another metal. The energy of photon carrying corresponding to threshold frequency (ν0) is E =hf0 where f0 = Threshold Frequency h … Read more
