What is the definition of a sound wave in middle school science?

• A type of electromagnetic wave that travels through space.

• A disturbance that travels through a medium, typically air, as a longitudinal wave.

• A wave that requires no medium to travel.

• A wave that travels only in water.

Which of the following best describes frequency in the context of sound waves?

• The distance between two consecutive crests of a wave.

• The number of waves that pass a point in one second.

• The height of a wave from its rest position.

• The speed at which a wave travels through a medium.

How is wavelength defined in middle school science?

• The time it takes for one complete wave to pass a point.

• The distance between two consecutive points in phase on a wave, such as crest to crest.

• The number of waves that pass a point in one second.

• The height of a wave from its rest position.

What does amplitude refer to in the context of sound waves?

• The speed at which a wave travels through a medium.

• The number of waves that pass a point in one second.

• The height of a wave from its rest position, indicating the wave's energy.

• The distance between two consecutive crests of a wave.

What does it mean for two quantities to be proportional in middle school science?

• They have no relationship to each other.

• As one quantity increases, the other decreases.

• As one quantity increases, the other increases at a constant rate.

• They are equal in magnitude.

How is velocity defined in the context of wave motion?

• The number of waves that pass a point in one second.

• The speed and direction of a wave as it travels through a medium.

• The height of a wave from its rest position.

• The distance between two consecutive crests of a wave.
