Refraction of Light
- Refraction: Bending or change in the direction of light as it passes from one medium to another
- Refraction of light occurs because of change in the speed of light due to a change in the medium.
- When light enters an optically denser medium from an optically rarer medium, the speed of light slows down and light bends towards the normal.
- The opposite happens when light enters an optically rarer medium from an optically denser medium.
