440 Hz tuning fork set with resonance box, hammer and counterweight

Function

Intended for experimental study, physics laboratory, carrying out physics and natural science experiments on: Sound. Sound, a longitudinal mechanical wave. What is meant by tuning fork. Some applications of tuning fork. Sound, a longitudinal mechanical wave. The propagation of sound through different mechanical media. The speed of sound depends on the medium in which it propagates. The propagation of sound through a solid. The propagation of sound through a liquid. The physiological qualities of sound, height of the sound wave, timbre and intensity. Sound, phenomena of interference, resonance and beat. Sound, Doppler effect. Low and high-pitched sound, etc.
