Brainpop Video: Light

There are two different types of light Natural lights, like the sun or even some animals which can make light from chemical reactions, and artificial lights, and there are two ways to make this type of light; by heating something to make it lit up light like candles or running an electric current through a solid like light bulb filament, and gas(neon). Artificial light is caused when matter shows energy in the form of light rays. We can also see thanks to light, light hits visible things and bounces off, this gets reflected into our eyes, which is how we see. As I said from the video summary before, light can travel through empty space. Light compared to anything or anyone travels fast, as fast as 300million meters in one second. Light can be reflected to bounce off and travel another way, but always straight, although light doesn't always exactly travel straight. Because when light travels through a transparent matter it bends/refracts but when the light is out of that "boundary" it heads straight again, this happens because light travels in different speeds, light travels slower therefore the line of rays bend. But, one like lightening is a electrical effect, which releases lot's of energy as a form of light.
