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. Echo and reverberation of sound. 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 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 apexes and nodes, indicated by cork powder, in a closed tube. The apexes and nodes indicated by cork powder. Mechanical waves on strings. The standing wave on a vibrating taut string. What is meant by a wave pulse. The standing wave resulting from the interference between the incident and reflected wave. The apexes and nodes of the standing wave. The reflection and interference of the incident and reflected transverse waves. The harmonic wave. The speed of propagation. Comparing standing waves on two different vibrating taut strings. The standing wave on a vibrating taut compound string. Taylor's expression applied to a vibrating string, with a tensiometer. The transport of energy in a mechanical wave. Taylor's equation for the speed at which a vibration propagates in a string. Taylor's expression on vibrating strings of different linear densities, with a tensiometer. Mechanical waves on springs. Standing wave along a helical spring. Visualizing the apexes and nodes of the wave on a spring. Energy transport in a mechanical wave. Standing waves along helical springs, with tensiometer. Mechanical waves in plates. Chladni resonant plate figures, vibration mechanics. Vibratory phenomena in metal plates. Observing and listening to the sound in the bellies and nodes of a square plate that oscillates subjected to different excitation frequencies. Observing and listening to the sound in the bellies and nodes of a circular plate that oscillates subjected to different excitation frequencies, etc.
