Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R.
In the light of the above statements, choose the most appropriate answer from the options given below.
| Assertion A : | The photoelectric effect does not takes place, if the energy of the incident radiation is less than the work function of a metal. |
| Reason R : | Kinetic energy of the photoelectrons is zero, if the energy of the incident radiation is equal to the work function of a metal. |
Official answer
(2)
Both $\displaystyle \mathbf{A}$ and $\displaystyle \mathbf{R}$ are correct but $\displaystyle \mathbf{R}$ is not the correct explanation of $\displaystyle \mathbf{A}$
