The behavior of light is explained by a combination of Ray Theory and Wave Theory. Historically, light was studied as rays; progress in electromagnetic theory led to the understanding of light as an electromagnetic radiation and wave theory of light.
The energy of light delivered per second is measured in Watts. The brightness of a light source in a given direction, its luminance or luminous intensity, is related to the power of light per unit of area.
The speed of light is one of the fundamental constants of physics and is measured as exactly 299,792,458 metres per second or 1,079,252,848.8 km/h.
When light passes from one medium to another of different density, its path of travel is bent. This phenomenon is known as refraction.
