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

Correct answer

0

Step-by-step solution

An electron will be emitted only when the frequency of light is more than the threshold frequency. As the frequency increases, K.E will increase linearly. The graph will be a straight line not passing through origin hence this is not a correct representation. So, this is the correct option. The number of emitted electrons will depend upon the number of the photons but not on the energy and frequency of the photons.
