Mission SM2 Characteristics of Sound Waves

High-pitched sounds are characterized by sound waves that have a _____. List all that apply ... .

Pitch is the sensation of an observer to a sound's frequency level. A high frequency sound wave is perceived to be a high pitch sound. A low frequency sound wave is perceived to be a low pitch sound.

The frequency (f) of a wave and the period (T) of a wave are mathematically related by the following formula:

As stated in the Dictionary section, pitch is directly related to the frequency of a sound. But pitch might be related to other wave properties as well. After all, the frequency of a wave is inversely related to the wavelength of a wave and inversely related to the period of a wave. (See Formula Frenzy section.) So relatively high frequency sounds are also relatively low wavelength sounds and relatively low period sounds.
