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.
It is based on the principle that conductivity of a semiconductor enhances with increase in the intensity of incident light. In this, a thin layer of some semiconductor (as
