Key concepts
3 concepts
- 1
When light bounces off a surface, it is called reflection, and the angle at which it hits the surface is the same as the angle at which it leaves.
- 2
Absorption occurs when light's energy is taken into a material as heat, which is why a black shirt feels warmer than a white shirt.
- 3
Refraction is the bending of light as it passes through different mediums due to changes in speed, which is why objects in water may appear bent.
