3.  All light is a form of energy. That’s because light “radiates”, or spreads out, in all directions from its source. (Such as a light bulb or star).

4. Light travels in a straight line until something interrupts it or changes its path

5.  When light hits an object, the rays either pass through it, bounce off it, or are absorbed by it.

6.  Light rays that bounce back are called reflected light.  The image that is created when light reflects is called reflection.

7.  When light bends, it is known as refracted light.  As light passes through two different substances of different densities, the speed of light is changed. This causes the light rays to change direction causing the “bending” effect.

8.  A material that allows almost all light to pass through it is described as transparent.

9.  When only a little light is allowed through, the object is considered translucent.

10.  A material that does not allow light to pass through is called opaque.
