Question

Assertion: Higher is the refractive index of a medium or denser the medium, the velocity of light in that medium. Reason: Refractive index is inversely proportional to explain with how ?​

Answer 1

Answer:

(A)

Explanation:

If the refractive index of the medium is high (denser medium) the velocity of the light in that medium will be small. (R): Refractive index of the medium is inversely proportional to the velocity of the light. - (a) Both the assertion and the reason are true and the reason is the correct explanation of assertion
