Question

Draw ray diagrams to show the refraction of a light ray from rarer to denser medium .


Pls make it fast.. The first who made it would be brainlist..​

Answer 1

Answer:

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)

the refraction of a light ray from rarer to denser medium.

When the ray of light travels from rarer to denser medium, the velocity of light increases. This causes the light to bend away from the normal.
