Light is an electromagnetic wave that travels without any medium. It can carry energy and information. Click to the left to find out more. |  |
Visible light is only a small part of the electromagnetic spectrum. Press the prism to the left to see the rest. |
 |
Light, sound and all waves obey the law of reflection. |
 |
Waves are refracted when they pass from one medium to another that has a different speed of propogation. |
 |
The intensity of electromagnetic waves from a point source decreases according to an inverse square law. |  |
Modulation allows information to be carried by electromagnetic waves. |
