Properties of a light wave

• Reflection: light bounces off the object

• Refraction: bending of light - when the light moves from one medium to another (air to water)

• Transmitting: light goes through an object

• Absorbing: Light soaks into something

How does light travel through objects?

• tranparent: all light travels through the object.

• translucent: some light travels through the object.

• opaque: no light travels through the object
