Sound

A self-checking practice quiz on sound for an algebra-based physics course: the nature of sound, the speed of sound, pitch and loudness, sound intensity and the decibel scale, the Doppler effect, standing waves in strings and pipes, resonance and harmonics, and beats. Every question is multiple choice and shown one at a time, and the set is drawn fresh each time you take it. At the end you receive a report showing how many you answered correctly.
