Refraction
- Refraction is the bending of light which occurs when it enters
a different medium
- Light travels at different speeds in different media e.g. it is
slower in a glass and water than what it is inside a vaccum
- Media in which light travels slower are aid to be
optically dense
- It is the changing of speed which causes light to refract
- When light enters a more optically dense material it refracts
towards the normal
- When light exists a more optically dense material it
refracts away from the normal
