Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400–700 nm, or perhaps 380–750 nm ). In physics, the term light sometimes refers t...

Every wavelength of light corresponds to a color which was assigned by people for easier recognition. The longer wavelengths appear as red while the shorter visible wavelengths appear as blue or violet.

The example of the photographic camera demonstrates that the light emitted or reflected by one object is able to change the physical state of a body (the film). Hence light carries energy. What can light therefore be? ... The speed of the wave is then found by multiplying the wavelength L by the frequency f.

Light waves come in many sizes. The size of a wave is measured as its wavelength, which is the distance between any two corresponding points on successive waves, usually peak-to-peak or trough-to-trough (Figure 1). The wavelengths of the light we can see range from 400 to 700 billionths of a meter.

The Spectrum of Visible Light ... The visible part of the spectrum may be further subdivided according to color, with red at the long wavelength end and violet at the short wavelength end, as illustrated (schematically) in the following figure.

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength.
