Question

with the help of diagram show how refraction take place (5) from denser to rarer medium and from rarer to denser medium​

Answer 1

Explanation:

Hey friend

Your answer is in the attachment please refer it ..

Rarer medium: The medium in which light travels with comparatively high speed in two given mediums.

Denser medium: The medium in which light travels with comparatively less speed in two given mediums.

Here,

In case 1: When light travels from Denser to Rarer medium, it's speed is changing from low to high so it goes away from the normal and the angle of incidence is less than the angle of refraction.

In case 2: When light travels from Rarer to Denser medium, it's speed is changing from high to low so it goes closer to the normal and the angle of incidence is more than the angle of refraction.

Please mark it as brainliest if it helps.
