Light is an electromagnetic spectrum that is visible to the human eye, we also call it visible light. It has a wavelength range from 380 (violet) to 740 (red) nanometers. The properties of light are reflection, refraction, diffraction, absorption, polarization and dispersion. Incident light can be reflected in the surface. If the surface is transparent, the light can enter and be refracted. The refracted light can have varying wavelengths. If that happens, there will be a dispersion of light and the manifestation of it is the production of colours. Light can also be a source of energy and can be absorbed and be dissipated as other forms of energy such as heat. Diffraction is the bending of incident light waves around barriers in its path. Lastly, light can be directed to vibrate in a specific plane and therefore called the plane polarized light.
