Light and Sound Waves

What is light defined as in the context of the provided material?

• A disturbance that transfers energy from one place to another without transferring matter.

• Electromagnetic radiation that you can see.

• The maximum extent of the repeating quantity from equilibrium.

• A material through which light does not pass.

According to the material, what is a concave mirror?

• A mirror that curves outward.

• A mirror that curves inward.

• A lens that is thicker in the middle than at the edges.

• A transparent object with at least one curved side that causes light to change direction.

What is the law of reflection?

• The angle of reflection is equal to the angle of incidence.

• The reflection of light from a rough surface.

• The change in direction of a wave as it changes speed in moving from one medium to another.

• The point where light rays parallel to the optical axis converge after being reflected by a mirror or refracted by a lens.

What is the definition of frequency in the context of waves?

• The perception of how high or low a sound is.

• The number of times the pattern repeats in a given amount of time.

• The transfer of energy from a wave to the medium through which it travels.

• The passage of a wave through a medium.

What does pitch refer to in terms of sound waves?

• The bouncing of a wave off a surface.

• The change in direction of a wave when it travels by the edge of an object or through an opening.

• The perception of how high or low a sound is; related to the frequency of a sound wave.

• The transfer of energy from a wave to the medium through which it travels.

What is reflection in the context of wave behavior?
