What is refraction?

Back

Refraction is the bending of light when it moves from one medium to another, such as from air to water.

Front

What is reflection?

Back

Reflection is the bouncing of light off a surface.

Front

What happens to light rays when they travel from water to air?

Back

Front

What does light travel in?

Back

Light travels in a straight line until it encounters an object or a different medium.

Front

How does refraction affect the appearance of objects in water?

Back

Objects appear distorted or different in size when viewed through water due to the bending of light rays.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing of light off an object, while refraction is the bending of light as it passes through different materials.

Front

What is a medium in the context of light?

Back

A medium is a substance through which light travels, such as air, water, or glass.

Front

Can light be absorbed by objects?

Back

Yes, some objects can absorb light, preventing it from being reflected or refracted.

Front

What is an example of refraction in everyday life?

Back

A straw appearing bent when placed in a glass of water is an example of refraction.
