Answer 2

Answer:

Refraction of light is the bending of waves when it enters a medium where it's speed is different. When a medium travels from a rarer to denser medium the light ray bends towards the normal and when it travels from a denser to rarer medium it bends away from the normal.

Example- The image of a pencil when dipped in water is different because the portion dipped in water bends away from the normal.
