A sound wave is a mechanical wave.

• True

• False

Sound can travel through a vacuum.

• True

• False

Intense sounds are usually perceived as loud sounds.

• True

• False

The speed of a sound wave depends upon its frequency and its wavelength.

• True

• False

Sound waves travel fastest in solids (compared to liquids and gases) because solids are more dense.

• True

• False

The speed of a wave within a guitar string varies inversely with the tension in the string.

• True

• False

A high pitched sound has a low wavelength.

• True

• False

A low-pitched sound is a sound whose pressure fluctuations occur with a low period.

• True

• False

Both low- and high-pitched sounds will travel through air at the same speed.

• True

• False

What type of wave is produced when the particles of the medium are vibrating to and from in the same direction of wave propagation?
