Air wave and spring assembly

Função

Intended for the study of physics, laboratory physics experiments on: Sound. 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 a wave. A wave only transports 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 with 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 by listening inside the tube. Emitting sound with 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.
