How do Light form?
 Light is a form of energy called electromagnetic radiation, which travels as invisible waves. Our most important source of Light is the Sun, but Light can be also be produced artificially using electricity or fire. Lenses and mirrors enable us to use Light to form images and to see tiny or distant objects.
Speed of Light
Light travels through spaces with an amazing speed of 299,792.5 km/s(186,287.5 miles/s). Light travels more slowly in different substances: in water, for example, it travels at about 225,000 km/s, and in glass at about 200,000 km/s. Light always travels in straight lines called rays, but its direction can be deflected by objects in its path.
