Light is emitted from many different sources. It comes from the

Light is emitted in to forms, particles and waves. The particles are
called photons. Light comes in both forms. This is called the dual nature of
frequency of visible light is very small it comes in 7 main wavelengths. Red

source of energy witch we can use to to replace gasoline.
Light is a small part of the energy spectrum. It is the middle range and
beside it is ultra-violet and infa-red. The extremes of this range are gamma
radiation and microwaves. Both of these are lethal to us, even though they
have very useful for cooking and energy.
colors. This is called a spectrum. These seven colors make up all the colors
we can see. Color is just a particular wavelength of light. Color is just a
wavelength of light that is not reflected by an atom of a substance. For
example a red item will reflect red light and absorb all the other and a blue
object will reflect blue light and absorb all other light.
When you mix all the different light colors together you get white
with some blue in it.
Light will boucle off an object at the opposite angle in witch it hit the
object. If it hits at 90 degrees it will bounce off at 90 degrees. Light does not
loose speed or energy when it hits an object.
