When light travels from air to glass, it bends towards the normal. This is an example of:

• Refraction

• Absorption

• Diffraction

• Reflection

What happens to the speed of light when it travels from air to water?

• The speed of light becomes invisible

• The speed of light remains the same

• The speed of light decreases

• The speed of light increases

What is the law of reflection?

• The angle of incidence is equal to the angle of reflection.

• Reflection occurs at a random angle.

• The law of reflection only applies to curved surfaces.

• The angle of incidence is greater than the angle of reflection.
