The sun is the source of energy on which all life on earth depends.

There are various kinds of solar energy: the sunlight enables us to see, we feel the warmth of the sunshine on our skin, and under the influence of the sun our skin is tanned.

These three effects are due to three specific components of the sun radiance spectrum, each of the components having their own wave lengths.

The sun radiates electro-magnetic vibrations with widely different wave lengths. The wave lengths of heat rays or "infrared" (IR) are longer than the wave lengths of visible light. And the wave lengths of "ultraviolet" (UV), which tans our skin, are shorter than these.

Science has managed to reproduce these three kinds of solar radiation: heat (e.g. Infraphil), light (lamps) and UV (solariums, sun couches etc.)

UV-A, UV-B and UV-C

Ultraviolet (UV) is subdivided into UV-A (longer wave lengths), UV-B and UV-C (shorter wave lengths).

UV-C seldom reaches the earth as it is filtered out by the atmosphere.

UV-A and UV-B cause the tanning effect of the skin.

In fact there are two processes which produce tanning, and they are simultaneously effective:
