Write Einsteins's photoelectric equation.

Write Einstein's photoelectrical equation in terms of the stopping potential and the threshold frequency for a given photosensitive material. Draw a plot showing the variation of stopping potential vs the frequency of incident radiation.

According to Einstein's photoelectric equation, the graph between kinetic energy of photoelectrons ejected and the frequency of the incident radiation is :

What is Einstein's photoelectric equation? Explain how it satisfies the various laws of photoelectric effect?

Draw a graph showing the variation of stopping potential with frequency of incident raditions in relation to photoelectric effect. Deduce an expression for the slope of this graph using Einstein's photoelectric equation.
