Technically black is not a color, but rather the absence of light. What happens to light waves when they strike on an object that appears black?

• all the light is reflected

• all the light is refracted

• all the light is diffracted

• all the light is absorbed

The Law of Reflection states that the Angle of Incidence will always be ... reflected off a smooth surface.

• greater than the Angle of Reflection

• smaller than the Angle of Reflection

• equal to the Angle of Reflection

• unknown. There is no relationship between these angles.

When Mr. Frank yells at his students, kids in the hallway can hear him even though the door is closed. Which property of sounds allows sound waves to travel through the small opening at the bottom of the door?

• Reflection

• Absorption

• Refraction

• Diffraction

What happens to light waves after they are absorbed?

• The light energy is converted to UV radiation.

• The light energy is converted to gamma radiation.

• The light energy is converted to thermal energy.

• The light just “disappears”.
