Question

draw a diagram showing that a light ray passing through denser medium to rarer medium​

Answer 1

The bending of light when it passes from rarer medium to denser medium is called refraction.

Hope it helps u

Answer 2

Ray diagram for a light ray travelling from denser medium to rarer medium:

• When a light ray travels from one medium to another, it appears to bend at the interface.
• This phenomenon is called as refraction.
• When a ray of light travels from denser medium to rarer medium, the velocity of light increases.
• This causes the light ray to bend away from the normal.
• In this case, the angle of refraction is greater than the angle of incidence(i<r).
