As a ray light ray travels from a less dense to a more dense optical medium (e.g. air to glass)
|
|
the incident ray travels straight on
|
|
|
the incident ray bends away from the normal
|
|
|
the incident ray travels down the normal
|
|
|
the incident ray bends towards the normal
|
Explanation:
Detailed explanation-1: -Refraction of Light: as it passes from more dense to less dense mediums. The bending of light as it passes from one medium to another is called refraction.
Detailed explanation-2: -When light enters a more dense substance (higher refractive index), it ‘bends’ more towards the normal line. The amount of bending depends on two things: Change in speed – if a substance causes the light to speed up or slow down more, it will refract (bend) more.
