Reflects some light and transmits some

4

Transparent

See through and transmits all light

5

Opaque

Absorbs all light

6

Luminous

7

Regular reflection

Light reflected on a smooth surface

8

Diffuse reflection

Light reflected in different directions on a rough surface

9

The difference between regular and diffuse reflections

Regular is a reflection upon a smooth surface and diffuse is a reflection upon a rough surface.

10

The law of reflection

The angle of incidence is equal to the angle of reflection

11

Refraction

When the speed of light through a medium with a different density effects the direction in which the light is travelling

12

Refractive index

The ratio that shows the difference in velocity between light in a vacuum and light in a denser medium
