It was only after less than 100 years after Newton’s discovery that another scientist, James C. Maxwell, brought forth the electromagnetic theory of light. Maxwell demonstrated that light was electromagnetic radiation. Electromagnetic radiation consists of self-sustaining oscillations of electric and magnetic fields that are at right angles to one another and the direction of propagation. These radiations do not require a supporting media and can travel in a vacuum at the speed of light (Brill, 452).&nbsp. The radiations consist of radio waves, infrared, visible light, ultraviolet, x-rays, and gamma rays, as shown in Figure 1.

The visible region forms a very small part of the spectrum. The radiations emitted by the sun falls within the visible region and extend into the infrared region beyond the red wavelength and ultraviolet region.

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. As an electromagnetic wave, each colour can be identified by its wavelength. Light can as well be described as a stream of energy packets called photons which create an energetic electromagnetic disturbance. Photons of different colours differ in energy and therefore can be distinguished from each other. The most convenient unit to measure the energy of light is the electron volt (eV). An electron volt is an energy that is acquired by a single electron that moves across a positive voltage of one volt (Smith, &nbsp.322).

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Photons of visible light have an energy content that ranges from 2 to 3 eV. The energy of light is inversely proportional to the wavelength, meaning that as the energy increases, the wavelength decreases and vice versa, as shown in Figure 2 below.It is clear from Figure 2 above that photoreceptors in the human eye can only be triggered by the energy of 1.8 to 3.1 eV. Special infrared detectors can only detect wavelengths of lower energies while those with higher energy can be detected by photographic film or other special apparatus. White light consists of all the colours of the rainbow since it contains all the wavelengths and therefore it is described as polychromatic light.
