Properties of sound waves

What is the term used to indicate how fast a wave moves through a medium

• frequency

• speed

• wavelength

• amplitude

What is the term used to indicate how long a wave is?

• frequency

• amplitude

• wavelength

• period

The time taken for the particles to complete a vibrational cycle

• frequency

• period

• wavelength

• speed

The pitch of a sound is directly related to the ______________ of a sound wave

• frequency

• wavelength

• speed

• amplitude

High pitched sounds have relatively large _________________ and small ________________

• period, wavelength

• speed, period

• period, frequency

• frequency, wavelength

As the frequency of a sound increases, the wavelength __________________ and the period __________________.

• decreases, increases

• increases, increases

• increases, decreases

• decreases, decreases

A sound wave is described as being 384 waves/s. This quantity describes the waves

• freqeuncy

• period

• speed

• wavelength

The speed of a sound wave depends upon the _________________

• frequency of the wave

• amplitude of the wave

• wavelength of the wave

• properties of the medium through which it moves

If a person yells, then it will cause

• air molecules to vibrate more frequently

• the sound wave to travel faster

• air molecules to vibrate with greater amplitude

A sound wave with a characteristic pattern of compressions and rarefactions is shown. A centimeter ruler is included. The wavelength of this sound wave is approximately:

• 1 cm

• 1.5 cm

• 2.0 cm

• 2.5 cm
