Sound Waves

A sound wave is a mechanical wave.

Sound can travel through a vacuum.

Intense sounds are usually perceived as loud sounds.

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

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

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

A high pitched sound has a low wavelength.

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

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

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