1

Refraction

The bending of light waves as they slow down as they pass through a different medium.

2

Specular reflection

When light travels in a straight line then hits an object and bounces off it.

3

Speed of light

The speed of light is 300,000,000 m/s.

4

Diffuse scattering

When light hits a surface than isn't flat reflect at the same angle it came in at.

5

Plane mirror

9

Trough/peak/crest

Angle of refraction

It passes through a different medium into a more dense substance this causes it to change direction and change shape.

11

Medium

A medium is a solid, liquid or gas.

12

Lens

Lens is are in both cameras in eyes in the eye it focuses light onto the retina and in the camera it focuses light onto the photosensitive lens.
