we already revived about the Electromagnetic waves.now we are going to have a glance on one of the type of electromagnetic waves(radiation) called LIGHT.
Generally we considered light as the energy which is responsible for the sence of sight.
we can see any thing(objects) because of the reflected light from the object which is captured by the retina of the eye.hence light is responsible for the sense of sight.

In general the wave length of the visible light varies from 400-700 nano-meters.which travels with a speed of 3*10 power 8 meters per second. behind the wavelength i.e.,less than 3 nano-meters it is called ultraviolet radiation(light),and after 700 nano-meters it is called as infrared radiation(light) which are not visible to naked eye.
hence the only light visible to naked eye is from 400-700 nano-meters.

even there is separation in the visible light (white light) which is the combination of seven colors (VIBGYOR) which is called visible spectrum.which can be seen through some special techniques like refraction's and even more.
The term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays,X rays,micro waves and radio waves are also light. 

visible light is emitted and absorbed in tiny "packets" called photon and exhibits properties of both waves and particles This property is referred to as the wave-particle duality.

this study of light further given way for some other very precious subjects like optics,ray optics etc.
