Function

Intended for experimental study, physics laboratory work, and conducting physics experiments on: Physics. Mechanical waves. Mechanical waves in air. Acoustics. Sound sources, sound, noise, and the physiological qualities of sound. What is sound? The frequency of a sound wave, high-pitched and low-pitched sounds. Auditory intensity, a physiological quality associated with the amplitude of sound. The difference between auditory intensity and the sound intensity of the wave. A wave only transports energy. Undesirable sounds, industrial noise. Sound reverberation. Echo and the minimum distance for an observer to perceive an echo. Sound reverberation and acoustic comfort. Reverberation time. Sound beats, the result of superimposed waves with a small difference in frequencies. Sound beat, constructive and destructive interference between two component waves. The sound resulting from the superposition of two sound waves. Measuring and calculating the average period and frequency of beats. The ratio between the period of the beats and each of the periods of the component waves. How does the period of the beats relate to the periods of the component waves? How does the frequency of the beats relate to the frequencies of the component waves? Standing sound waves in an open tube, resonance. Sound, a mechanical, longitudinal, and three-dimensional wave. What is meant by a closed sound tube and an open sound tube? Sound and wave interference, the standing wave in an open tube. The fixed points of constructive and negative interference, the nodes and antinodes of the standing wave. The speed at which sound propagates in a mechanical medium. Timbre. Auditory intensity, with an observer intervening. The antinodes and nodes of the standing sound wave, listening inside the open sound tube. Determining the speed of sound in a sound tube, Kundt's tube, open. The positions of the antinodes and nodes, indicated by cork dust, in an open tube. Standing sound waves in a closed tube, resonance. The speed at which sound propagates in a mechanical medium. Some factors that influence the speed of sound. The antinodes and nodes of the standing sound wave, listening inside the sound tube. Determining the speed of sound in a closed sound tube. The positions of the antinodes and nodes, indicated by cork dust, in a closed tube. The antinodes and nodes indicated by cork dust, etc.
