15.1 The Electromagnetic Spectrum
The colors on the subtractive color wheel are made by pigments that absorb all colors but one. Therefore, when these colors all overlap, all light is absorbed and the result is black. White light is a combination of all colors, so when all colors are added together on the additive color wheel, the result is white.

The red laser light is emitted at approximately 2 electron volts eV, which is necessary to energize the trapped electrons. This extra energy allows the trapped electrons to escape the active layer where they emit visible blue light at an energy of 3 eV as they relax into lower energy levels (Figure 4-10). As the imaging plate moves through or ...

Colours of light
White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light. Light from a torch or the Sun is a good example of this. Light from a laser is monochromatic, which means it only produces one colour. (Lasers are extremely dangerous and can cause permanent eye damage.
