- Light is electromagnetic so it consists of oscillating electric and magnetic fields. The visible part of the spectrum has a wavelength range of 3.7 × 10−7 —7.4 ×10−7m. All electromagnetic waves have a speed of 3.0 × 108 m s−1 in a vacuum. Light can be reflected, refracted, diffracted, polarised (polarized in US English), and superposed.

These different colours of light have different wavelengths and frequencies. Red light has the longest wavelength, and the lowest frequency of the visible spectrum. Violet has the shortest wavelength, and the highest frequency of the visible spectrum.
Mixing coloured materials, such as paint, is an example of subtractive colour mixing. Red paint appears red to us because when white light strikes it, the red pigments reflect the red wavelengths of light and absorball of the wavelengths. This reflected light is what is seen by our eyes. The same is true for all of the other colours. So what about ...
Light travels very fast - at the speed of light in fact!Light travels as waves.Light travels in straight lines.Light and Its Optical Properties. Light is a form of energy that is in the form of an electromagnetic wave and is almost everywhere around us. The visible light has wavelengths measuring between 400–700 nanometres.
