vibrations and waves

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

Simple harmonic motion is the back and forth motion of a

• wave
• pendulum
• vibration

Whenever the motion of the medium is perpendicular (at right angles) to the direction the wave is traveling, then the wave is said to be

• transverse
• longitudinal
• rotational

when particles of the medium move back and forth in the same direction that the wave is moving then the wave is said to be

• Longitudinal
• Transverse
• Constructive
