Vedclass · Answer

(A) Newton's corpuscular theory suggests that light consists of tiny particles called corpuscles.According to this theory,the velocity of light increases as it enters a denser medium because the particles are attracted by the medium.However,experimental evidence shows that the velocity of light is lower in a denser medium compared to a rarer medium.Therefore,the corpuscular theory fails to explain the observed velocities of light in different media.Since the reason correctly explains why the theory fails,both statements are correct and the reason is the correct explanation of the assertion.Thus,option $(A)$ is correct.

Column-$1$	Column-$2$
$(a)$ Speed	$(i)$ Increases
$(b)$ Its amplitude	$(ii)$ Decreases
	$(iii)$ Remains constant

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 medium than in rarer medium.
