Q Define threshold frequency?
The minimum frequency of incident radiation lower which the photoelectric emission isn't possible completely but high the intensity of incident radiation may be. The threshold frequency is dissimilar for different metals.
For a blackbody, the frequency at which maximum energy is emitted is 3 x 10 13 Hz: A. Give a wavenumber for the wavelength of the infrared emission? B. What is the tempe
