Light Review

Light travels

• around corners

• in a straight line (transverse waves)

• in loops, like a slinky (longitudinal waves)

Light bounces when it strikes a smooth and/or lustrous surface

• reflected

• absorbed

• refracted

Opaque objects allow no light through. This is an example of....?
