Light is electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10−11 metres to radio waves measured in metres.
the medium of illumination that makes sight possible. Also called: visible radiation electromagnetic radiation that is capable of causing a visual sensation and has wavelengths from about 380 to about 780 nanometres.
PROPERTIES OF LIGHT ?
The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature.
WAVE NATURE OF LIGHT ?
Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum.
