NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyGiven 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 correct answer from the options given below:
| 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. |
In the light of the above statements choose the correct answer from the options given below:
| 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. |
