Vibration waves and sound

Vibrations are known as:

• a wiggle in time
• back and forth movement
• wavelengths

A wiggle in both space and time is called:

• vibration
• back and forth movement
• wave

The time required for a pendulum to make one to-and-fro swing is known as the

• period
• crest
• frequency

The high point of a wave is called the

• crest
• trough
• cycle

The low point of a wave is called the

• trough
• crest
• amplitude

The distance from the midpoint to the maximum (crest) of a wave, or from the midpoint to the minimum (trough) is known as the

• crest
• amplitude
• wavelength

Wavelength is

• the distance from the top of one crest to the top of the next crest
• the distance from the bottom of the trough to the bottom of the next trough
• both

Frequency is

• the number of events per unit time
• the distance between the midpoint and crest
• positions where the largest amplitude occurs

Hertz is a unit of

• cycles per one second
• distance per unit time
• accleration
