The correct Answer is:
To solve the assertion and reason question, we will analyze both the assertion and the reason step by step. ### Step 1: Understand the Assertion The assertion states that "the angle of deviation depends on the angle of the prism." - **Explanation**: The angle of deviation (denoted as \( \delta \)) is the angle by which a ray of light is deviated from its original path after passing through a prism. The angle of the prism (denoted as \( A \)) is the angle formed between the two faces of the prism. - **Conclusion**: As the angle of the prism increases, the angle of deviation also increases. Thus, the assertion is **true**. ### Step 2: Understand the Reason The reason provided is "For a thin prism, \( \delta = (\mu - 1) - A \)." - **Explanation**: For a thin prism, the correct formula for the angle of deviation is given by \( \delta = (\mu - 1)A \), where \( \mu \) is the refractive index of the prism material. The reason given in the question is incorrect because it states \( \delta = (\mu - 1) - A \), which is not the correct formula. - **Conclusion**: Since the reason is incorrect, it is **false**. ### Step 3: Final Evaluation Based on the analysis: - The assertion is true. - The reason is false. Thus, the correct conclusion is that the assertion is true, but the reason is false. ### Final Answer - Assertion: True - Reason: False
