A light source produces light.
Sources of light…
What happens when light hits an object? The light is reflected off the object.
We see things because of reflected light.
We blue because blue is reflected; white because all colors are reflected.
We see ourselves in a mirror because of reflection.
The light that hits an object is called the angle of incidence. The light that bounces off the object is called the angle of reflection.
Angle of incidence = Angle of reflection Molecular Expressions
This is called the law of reflection. Molecular Expressions

When light passes thru transparent objects (water, glass, etc.), the light is refracted (bent).
When light passes thru water, it’s refracted.
When light travels thru a prism, the refraction forms the spectrum. DiscoveryEducation Clipart
The spectrum is the colors of the rainbow…
Red, Orange, Yellow, Green, Blue, Indigo, and Violet (ROY G. BIV).

Three things can happen when light hits an object.
If the object is transparent, it will pass through it.
If the object is translucent, light is diffused as it passes through it. Designbuild-Network.com
If the object is opaque, the light will not pass thru the object and is reflected.

All About Light. Why does the straw look bigger in the water? Because water magnifies the size of an image. Because light travels slower through the water.

WHAT IS LIGHT? Light arrives on our planet from the Sun, (93 million miles away). Light travels at 186,000 miles per second, so the light you're seeing.

Light Absorption. When light travels, we know that it can bounce (reflect) or bend (refract) off of objects, but do you think it can do anything else?
Light Objects can absorb light, reflect light, and allow light to pass through them. The type of matter in an object determines the amount of light it.
