(C) According to Einstein's photoelectric equation,the kinetic energy $(K.E.)$ of the ejected electron is given by: $K.E. = h
u - h
u_0$,where $h
u$ is the energy of the incident photon and $h
u_0$ is the work function of the metal.$1$. The relationship between $K.E.$ and energy of light $(h
u)$ is a straight line with a positive intercept $(-h
u_0)$,which matches graph $(A)$.$2$. The number of ejected electrons depends on the intensity of light,not the frequency (above the threshold),so graph $(B)$ is a valid representation.$3$. The relationship between $K.E.$ and frequency $(
u)$ is $K.E. = h
u - h
u_0$. This is a straight line with a negative intercept on the $K.E.$ axis,not one passing through the origin. Therefore,graph $(C)$ is incorrect.$4$. $K.E.$ is independent of the intensity of incident light,so graph $(D)$ is a valid representation.Thus,the graph that does not represent the relationship is $(C)$.

Which of the graphs shown below does not represent the relationship between incident light and the electron ejected from a metal surface?
