Inverse Square Law – When a surface is illuminated by a source of light, the intensity of the light at the surface is inversely proportional to the square of its distance from the light source. Fluorescent – Tubes radiate light after absorbing ultraviolet light from mercury vapor emission, resulting in a green cast not visible to the naked eye.
