Light Reflection, Refraction and Absorbtion

Front

What is light reflection?

Back

Light reflection is the bouncing back of light rays when they hit a surface, such as a mirror.

Front

What is light refraction?

Back

Light refraction is the bending of light rays as they pass from one medium to another, like from air to water.

Front

What is light absorption?

Back

Light absorption occurs when light is taken in by a material and does not pass through or reflect off it.

Front

What happens to light when it hits a mirror?

Back

When light hits a mirror, it reflects off the surface at the same angle it arrived.

Front

Why does a straw look bent in a glass of water?

Back

A straw looks bent in water because of refraction; light changes direction as it moves from water to air.

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.

Front

What is an example of light being refracted?

Back

An example of refraction is when a pencil appears broken when placed in a glass of water.

Front

What is a medium in terms of light?

Back

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

Front

How does light behave when it enters a denser medium?

Back

When light enters a denser medium, it slows down and bends towards the normal line.

Front

What is the normal line in light refraction?

Back

The normal line is an imaginary line perpendicular to the surface at the point of incidence.
