CP Waves Quiz 1

The source of all wave motion is a __________.

• movement of matter

• harmonic object

• region of variable high and low pressure

• vibration

How are frequency and period related in simple harmonic motion?

• They are inversely related

• Their sum is constant

• They are directly related

• Both measure the number of cycles per unit of time

A wave travels through a medium. As a result, the particles of the medium vibrate in a direction parallel to the direction of the wave’s motion. The wave is

• longitudinal

• transverse

• a pulse

• electromagnetic

Each compression in the waveform of the longitudinal wave shown above corresponds to what feature of the transverse wave below it?

• amplitude

• wavelength

• crests

• troughs

The distance from trough to trough of a wave is called its

• frequency

• period

• wavelength

• velocity

• amplitude

Which of the following types of interference will occur when the pulses in the figure above meet?

• total

• none

• constructive

• destructive

Which of the following types of interference will occur when the pulses in the figure above meet?

• total

• none

• constructive

• destructive

The amplitude of a particular wave is 1.5 meter. The top of the crest to the bottom of the trough distance of the disturbance is

• 0m

• 1m

• 2m

• 3m

What happens when these waves interfere with one another?

• the amplitude doubles

• they cancel each other out

• the wavelength decreases by half

• the amplitude decreases by half

If a police car is approaching you, the sound you hear

• has the same pitch as if it were not moving but gets to you faster.

• has the same pitch as if it were not moving but takes longer to get to you.

• has a higher pitch than if the car was at rest.

• has a lower pitch than if the car was at rest.
