Question

Incident ray: Rarer medium ::
:
Denser medium

​

Answer 1

Incident ray : Rarer medium :: Refracted ray : Denser medium

Let's see a detailed explanation:

• Let's assume an interface separating a rarer medium and a denser medium.

• In the rarer medium, the velocity of light is higher as compared to a denser medium.

Now, when the incident ray falls on the interface from the rarer medium, it undergoes refraction and the refracted ray passes on into the denser medium.

In the denser medium, the velocity of light decreases and the ray gets deviated towards the normal.

So, in the denser medium, we get to see the refracted ray.
