Question

Read both the statements carefully and choose the correct alternative
from the following:

ASSERTION: As the temperature of a medium increases the refractive index
decreases.
REASON: When a ray travels from vacuum to a medium, then is known as
absolute refractive index of the medium.

(a) Both the assertion and the reason are false.
(b) Both the assertion and the reason are correct, and the reason is the correct
explanation of the assertion.
(c) The assertion and the reason are correct, but the reason is not the correct
explanation of the assertion.
(d) Assertion is true, but the reason is false

Answer 1

Answer:

c

Explanation:

because when temperature increases the molecules move in random the light ray can travel in high speed.

1. speed is inversely proportional to refractive index
2. this is the reason

Answer 2
