• Visible light is a small band within a very broad electromagnetic spectrum.

• For an object to be seen, the eye must detect light emitted by or scattered from it.

• Light travels in straight lines if the medium it travels through does not change.

• Light can be reflected, refracted, transmitted, and absorbed by matter.

• The angle of reflection of a light beam is equal to the angle of incidence.

• Simple lenses are used in a magnifying glass, the eye, a camera, a telescope, and a microscope.

• White light is a mixture of many wavelengths (colors) and retinal cells react differently to different wavelengths.
