How is Refraction of light in different media? Draw images.

Here, you can see the refraction of light in different media:

1. The light ray bends towards the normal when it passes from a rarer medium to a denser medium.
2. A light ray bends away from the normal, when it passes from a denser medium to a rarer medium.

Finally,

1. A light ray does not change its direction nor does it get refracted if it is incident normally at the boundary between two media.
