Reflection, Refraction, Absorption

Front

What is Reflection?

Back

Reflection is the bouncing back of light waves when they hit a surface.

Front

What is Refraction?

Back

Refraction is the bending of light waves as they pass through a transparent medium.

Front

What is Absorption?

Back

Absorption is the process by which an object takes in light waves and does not reflect or transmit them.

Front

What color does an object appear if it absorbs all colors of light?

Back

Front

What happens to light when it hits a mirror?

Back

It reflects.

Front

What is the speed of sound in solids compared to liquids and gases?

Back

Sound travels fastest in solids.

Front

What is the law of reflection?

Back

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

Front

What is a transparent medium?

Back

A transparent medium is a material that allows light to pass through with minimal scattering.

Front

Give an example of refraction in everyday life.

Back

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

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 a medium.
