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

Correct answer

3

Step-by-step solution

The maximum kinetic energy of photoelectron ejected is given by KE =h v - ₀=h v -h v ₀=h ( v - v ₀ ) If the frequency of incident radiation is greater than threshold frequency v₀ , then the ejection of photoelectrons starts. After that as frequency increases, kinetic energy also increases linearly. It is shown in option (d).
