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 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 sound amplitude. Difference between auditory intensity and sound wave intensity. Waves only transport energy. Undesirable sounds, industrial noise. Sound reverberation. Echoes and the minimum distance for an observer to perceive an echo. Sound reverberation and acoustic comfort. Reverberation time. Standing waves in an open sound tube, resonance. Identifying the antinodes and nodes of a wave by listening inside the tube. Emitting sound with a frequency and measuring its wavelength. Determining the speed of sound in an open sound tube. Locating antinodes and nodes with cork powder. Emitting sound at a frequency, measuring the wavelength and calculating its speed. Standing sound waves in a closed tube, resonance. Sound, interference and standing waves in a closed sound tube. Identifying the antinodes and nodes of the wave, listening inside the sound tube. Emitting sound at a frequency and measuring the wavelength. Determining the speed of sound in a closed sound tube. The positions of the antinodes and nodes, indicated by cork dust, etc.
