CP Intro to waves

The source of all wave motion is a __________.

• movement of matter

• harmonic object

• region of variable high and low pressure

• vibration

Which of the following affects a pendulum’s period?

• weight

• angle

• length

• all of these

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

The time needed for a wave to make one complete cycle is its

• period

• frequency

• wavelength

• velocity

• amplitude

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

When two mechanical waves arrive in phase, the amplitude of the resultant wave is always ____ the amplitudes of each wave alone.

• greater than

• the product of

• less than

• the same as

• total

• none

• constructive

• destructive
