Sound Wave Properties and Characteristics Quiz

The frequency of a sound wave determines the pitch. A higher frequency corresponds to a higher pitch, while a lower frequency corresponds to a lower pitch.

The wavelength is the distance between two crests of a sound wave. The crest is the peak of the wave, while the trough is the lowest point. The amplitude is the distance between the crest and the trough.

The normal range of human hearing is from 20–20,000 Hz in terms of frequency, and 0–120 decibels (dB) in terms of loudness.
