light is a form of energy. it helps us see. according to wave theory of light, light is an electro-magnetic wave. that is it has both electric and magnetic fields.according to particle theory of light, it consists of photons (energy quanta or energy packet)...

Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight.[1] Visible light has a wavelength in the range of about 380 nanometres to about 740 nm ? between the invisible infrared, with longer wavelengths and the invisible ultraviolet, with shorter wavelengths.
