Understanding Light and Refraction

What is a medium in the context of light travel?

• A source of light

• A color of light

• A material through which light can travel

• A type of lens

What happens to light when it moves from air into water?

• It stops

• It changes color

• It bends

• It speeds up

Why do objects appear bent when placed in water?

• Because of absorption

• Because of reflection

• Because of diffraction

• Because of refraction

How can lenses be used in relation to light?

• To reflect light

• To change the color of light

• To focus or magnify light

• To absorb light

What causes a rainbow to form?

• Absorption of light

• Diffraction of light

• Refraction and dispersion of light

• Reflection of light
