• curves

• waves

• circles

• directions

When light is taken IN by an object, we say the light is

• Refracted

• Reflected

• Absorbed

When light bounces off an object, the light is

• Reflected

• Absorbed

• Refracted

The bending of light as it moves from one material to another is

• Absorption

• Reflection

• Refraction

A material that allows most of the light to pass through so you can easily see through an object is

• Translucent

• Transparent

• Opaque

Why do opaque objects appear to be colored?

• Light only contains one color

• All the colors are absorbed and none reflected

• They refract all the light that hits the object

• They reflect different waves of light to your eye
