Assertion : The energy \((E)\) and momenturn \((p)\) of a photon are related by \(p=E / c\) Reason : The photon behaves like a particle
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
\(E=h v=\dfrac{h v}{\lambda}\), but \(\lambda=\dfrac{h}{p}\) (by de Broglie) Therefore, the relationship between energy \((E)\) and momentum \((p)\) for a photon is \(p=\dfrac{E}{c}\). So correct option is (1).

Assertion : Photoelectric current depends on the intensity of incident light. Reason : Number of photoelectrons emitted per second is directly proportional to the intensity of incident radiation.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
The number of photoelectrons emitted per second is directly proportional to the intensity of incident radiation. So option (1) is correct.
