Assertion : `gamma`-rays are produced by the transition of a nucleus from some higher energy state to some lower energy state.
Reason : Electromagnetic waves are always produced by the transition process.

A

(a) If both Assertion and Reason are true and Reason is correct explanation of the Assertion.

B

(b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

(c) If Assertion is true, but the Reason is false.

D

(d) If Assertion is false but the Reason is true.

The correct Answer is:
To solve the question, we need to evaluate both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that gamma rays are produced when a nucleus transitions from a higher energy state to a lower energy state. - This is true because gamma rays are a form of electromagnetic radiation emitted by atomic nuclei during such transitions. When a nucleus loses energy, it can emit this energy in the form of gamma radiation. 2. **Understanding the Reason**: - The reason states that electromagnetic (EM) waves are always produced by a transition process. - This statement is partially true but misleading in the context of the assertion. While it is true that transitions can produce EM waves, the specific context of gamma rays involves the emission of energy when moving from a higher to a lower energy state. Conversely, when energy is absorbed (transitioning from lower to higher energy states), EM waves are absorbed, not produced. 3. **Conclusion**: - The assertion is correct: gamma rays are indeed produced by the transition of a nucleus from a higher energy state to a lower energy state. - The reason is incorrect in the context of the assertion because it implies that EM waves are always produced, which is not the case; they can also be absorbed. - Therefore, the correct answer is that the assertion is true, but the reason is false. ### Final Answer: - The assertion is true, and the reason is false. Hence, the correct option is C.
