Question

Observe the following diagram carefully and identify the statement that is correct as per this diagram.
(I) Speed of light in medium A is less than the speed of light in medium B
(II) The optical density of medium A is more than the optical density of Medium B
(III) The absolute refractive index of medium B is less than the absolute refractive index of medium A.
(IV) The absolute refractive index of medium B is higher than the absolute refractive index of Medium A​

Answer 1

Answer:

(IV) The absolute refractive index of medium B is higher than the absolute refractive index of Medium A

here light ray is bending towards normal so it is passing from rarer to denser medium

the refractive index of denser medium is great than rarer medium
