Introduction to Light

Light is a form of energy that travels in waves and can be seen by the human eye.

Opaque means that an object does not allow light to pass through it.

Translucent means that an object allows some light to pass through, but not enough to see clearly through it.

Transparent means that an object allows light to pass through it completely, so you can see clearly through it.

A toy car is an example of an opaque object.

A tissue is an example of a translucent object.

A window is an example of a transparent object.

A light source is an object that emits light, such as the sun or a light bulb.
