According to Einstein's photoelectric equation graph of kinetic energy of emitted photo electrons from metal versus frequency of incident radiation is linear .Its slope……

In an experiment of photo-electric effect, the graph of maximum kinetic energy E_(k) of the emitted photoelectrons versus the frequency v of the incident light is a straight line AB as shown in figure below : Threshold frequency of the metal.

In a photoelectric experiment, with light of wavelength lamda , the fastest electron has speed v. If the exciting wavelength is changed to 5lamda/4 , the speed of the fastest emitted electron will become

Assertion : The threshold frequency of photoelectric effect supports the particle nature of sunlight . Reason : If frequency of incident light is less than the threshold frequency , electrons are not emitted from metal surface.
