Cidepe

Function

Intended for experimental study, physics laboratory and carrying out physics experiments on: Mechanical waves. Acoustics. Sound sources, sound, noise and physiological qualities of sound. What is sound. The frequency of a sound wave, high-pitched sound and low-pitched sound. Auditory intensity, physiological quality associated with the amplitude of sound. Difference between the auditory intensity and the sound intensity of the wave. The wave only carries energy. Undesirable sounds, industrial noise. Sound reverberation. Sound echo and reverberation. Reverberation time. Sound beats, the result of superimposed waves with a small difference in frequency. 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 between the period of the beats and each of the periods of the component waves. How the period of the beats relates to the periods of the component waves. 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. The timbre. The 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 a sound tube, Kundt's tube, open. The positions of the apexes and nodes, indicated by the cork powder, 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 powder, in a closed tube. The bellies and nodes indicated by cork powder, etc.
