• Bouncing back of light when it strikes a surface

• Refraction of light when it changes direction

• Absorption of light by a surface

Explain how a mirror reflects light.

• Light hits the mirror and gets absorbed by the surface

• Light hits the mirror and bounces off the smooth surface at the same angle.

• The angle of reflection is different from the angle of incidence

• The mirror creates its own light to reflect the image

How does a prism demonstrate refraction of light?

• The prism has no effect on the light passing through it

• The prism absorbs the light and turns it into heat

• The prism reflects the light back in the same direction

• The prism bends or refracts the light, separating it into its different colors.

What are transparent, translucent, and opaque materials?

• Materials that are magnetic and conduct electricity

• Materials that are only visible in the dark

• Materials that change color in different light

• Materials that allow light to pass through completely, allow some light to pass through, and do not allow light to pass through at all.
