Wave Behaviors Practice

What happens to light waves as they pass through a concave lens?

• The light waves spread out

• The light waves are reflected

• The light waves are absorbed

• The light waves are focused toward a single point

Which statement BEST describes what happens when white light strikes the peel of an orange?

• the peel reflects orange wavelengths of light and absorbs all other colors

• the peel absorbs orange wavelengths of light and reflects all other colors

• the peel absorbs orange wavelengths of light and diffracts all other colors

• the peel diffracts orange wavelengths of light and absorbs all other colors

What happens to a light wave that is absorbed by matter?

• it is reflected from the surface of the matter

• it is refracted

• it bends around the matter

• its energy is turned into heat
