Cidepe

Function

Intended for experimental study, physics laboratory, and physics experiments on: Mechanical waves. Acoustics. Sound sources, sound, noise, and the physiological qualities of sound. What is sound? The frequency of a sound wave, high-pitched sound, and low-pitched sound. Auditory intensity, a physiological quality associated with sound amplitude. The difference between auditory intensity and the sound intensity of the wave. The wave carries only energy. Undesirable sounds, industrial noise. Sound reverberation. Sound echo and reverberation. Reverberation time. Sound beats, the result of superimposed waves with small frequency differences. Sound beats, 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 the beats. The ratio of the beat period to each of the component wave periods. How the beat period relates to the component wave periods. How the frequency of the beats relates 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 interference and negative interference, the nodes and apexes of the standing wave. The speed at which sound propagates in a mechanical medium. Timbre. Auditory intensity, with an observer intervening. The apexes and nodes of the standing sound wave, listening inside the open sound tube. Determining the speed of sound in an open sound tube, Kundt's tube. The positions of the apexes 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 apexes 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 bellies and nodes, indicated by cork dust, in a closed tube. The bellies and nodes indicated by cork dust, etc.
