The high importance of electromagnetic radiation for human life is well known. Following winter season, life on our earth retrieves vitality in early spring mostly by the sunrays reaching the ground. When white light enters a prism, it will divide into the well-known spectral colours: From red to orange, followed by yellow, changing to green as well as blue and finally showing the violet dye.
The scientist Isaac Newton (1642-1727) noticed this already in his mid-twenties [1]. This observation indicated that white light was a composition of the rainbow colours. Johann Wolfgang von Goethe (1749-1832) confirmed this discovery. The light spectrum is not exclusively detected in the rainbow. In the action of forging one can notice that iron, once it is heated by the fire, switches colours from dark to bright red. It ultimately alternates at last into white. Although not combustible, solid matter behaves in this manner. From this observation, it is clear that long-wavelengths appear at lower temperatures. As the temperature elevates, shorter wave-lengths are noticed until all wave-lengths are present in the incandescent substance. Examinations on extremely hot stars have demonstrated that long wave-lengths steadily vanish and the colour changes into the blue spectrum range.
The quantum theory of light is based on the scientific findings of Max Planck (1858-1947) as well as Albert Einstein (1879-1955) and clarifies the nature of light. They demonstrated the particle- and wave-like qualities of light. In 1803, the scientist Thomas Young (1773-1829) showed evidence of interference patterns in visible radiation. His experimental testing demonstrated that visible radiation is based on waves. This has already been shown by Christiaan Huygens (1629-1695). The electromagnetic theory of light was stated by James Clerk Maxwell (1831-1879). He explained light as a composition of electric and magnetic fields.
In 1900 the physicist Max Planck postulated that the electromagnetic spectrum is based on small discrete packets. These quanta are called photons, the most minuscule light particle .
Albert Einstein utilized this quality of light in order to explain the photoelectric effect. The Nobel Prize Committee decided in the year 1922, to honour Einstein for this discovery with the still open Nobel Prize in Physics of the year 1921 and not for his brilliant relativity theory developed a decade later. As a practical application, these theoretical findings on photoelectric effects allowed to quantify photons by sensitive photomultiplier systems.
By this sophisticated method it is possible now to detect a firefly at a distance of six and 4000 km.

Another application of this discovery can be seen in the automatic closure of the door of a lift. A beam of light in the door system hits the metal plate and therefore an electric current starts to flow in order to close the door. As soon as this process is interrupted by a person entering, this electric current stops and it is for this reason the door stays open..
