Study Notes
Refraction of Light
- Refraction is the phenomenon where light changes direction when it passes from one medium to another.
- Light bends when it exits a medium because of the change in speed caused by the difference in density between the two mediums.
- Medium refers to the substance through which light travels.
- Light travels more slowly in denser mediums.
- The change in speed between mediums causes the bending, or refraction, of light.
