The correct graph between the maximum energy of a photoelectron \(\left(K_{max}\right)\) and the inverse of the wavelength \(\left(\frac{1}{\lambda}\right)\) of the incident radiation is given by the curve:
1. | \(A\) | 2. | \(B\) |
3. | \(C\) | 4. | None of these |
Assertion (A): | The kinetic energy of the emitted photoelectrons for a given metal changes only with a change in the frequency of the incident radiations. |
Reason (R): | The kinetic energy of photo-electrons emitted by a photo-sensitive surface depends upon the intensity of the incident radiation. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
