AIIMS 2017 Physics Corpuscular Theory Assertion Reason Question
In the following questions, a statement of assertion is given followed by a corresponding statement of reason. Assertion: Corpuscular theory fails in explaining the velocity of light in air and water. Reason: According to Corpuscular theory is that light should travel faster in denser medium than rarer medium.
If both assertion and reason are true and reason is correct explanation of assertion.
If both assertion and reason are true and reason is not correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Option B is correct because both the assertion and the reason are true; however, the reason does not correctly explain the assertion. The assertion states that the corpuscular theory fails to explain the velocity of light in air and water, which is accurate since light travels slower in denser media, contrary to the predictions of the corpuscular theory. The reason is true in that it claims light should travel faster in denser media, but this contradicts the observed behavior of light, thus failing to justify the assertion.
Option A is incorrect because the reason does not provide a correct explanation for the assertion. Option C is incorrect as both statements are true. Option D is incorrect because both statements are factual.
