What is Reflection?

Back

Reflection is the bouncing back of light when it hits a surface. For example, when you look in a mirror, you see your reflection.

Front

What is Refraction?

Back

Refraction is the bending of light as it passes from one medium to another, like when light travels from air into water.

Front

Can you name a material that absorbs light?

Back

Yes, black materials absorb light, while white materials reflect it.

Front

What is the difference between Reflection and Refraction?

Back

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

Front

Give an example of Refraction in everyday life.

Back

An example of refraction is when a straw appears bent when placed in a glass of water.

Front

What is a real-life example of Absorption?

Back

A real-life example of absorption is how a sponge soaks up water.

Front

What is the Law of Reflection?

Back

The Law of Reflection states that the angle of incidence is equal to the angle of reflection.
