Light Energy 5.6C

Front

What is light energy?

Back

Light energy is a form of energy that travels in waves and can be seen by the human eye. It is responsible for making things visible.

Front

What happens to light when it hits a mirror?

Back

When light hits a mirror, it bounces back. This process is called reflection.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, causing it to change direction.

Front

What is a prism?

Back

A prism is a clear, triangular device made of plastic or glass that refracts light, separating it into different colors.

Front

What is a lens?

Back

A lens is a curved piece of glass or plastic that refracts light to focus or spread it.

Front

What is absorption in terms of light?

Back

Absorption is when light is taken in by a material and does not pass through or reflect.

Front

What is transmission in the context of light?

Back

Transmission is the process of light passing through a material without being absorbed.

Front

What is the medium in relation to light?

Back

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

Front

How does light behave when it travels from air to water?

Back

When light travels from air to water, it refracts, bending towards the normal line due to the change in medium.

Front

What is the normal line in optics?

Back

The normal line is an imaginary line that is perpendicular to the surface at the point where light hits it.
