Question

Assertion : Corpuscular theory fails in explaining the velocities of light in air and water.
Reason : According to corpuscular theory, light should travel faster in denser media than in rarer media.

• A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. If the Assertion and Reason are true but Reason is not correct explanation of Assertion
• C. If Assertion is true but, Reason is false
• D. If Assertion is false but, Reason is true

Answer 1

Answer: (A)

According to Newton's corpuscular theory of light, the light should travel faster in denser media than in rarer media. It is contrary to present theory of light which explains that light travels faster in air (rarer) than in water (denser).
