Air and spring wave assembly, analog and digital multimeter.

Function

Intended for experimental study, physics laboratory work, and conducting physics experiments on: Wave motion. Main characteristics of waves in a long helical spring. Mechanical waves. The longitudinal pulse and the transverse pulse. The characteristics of a wave. Energy transport in a mechanical wave. Determining the average propagation speed of a pulse in a long helical spring. The phenomenon of reflection and interference in a transverse wave in a spring and the standing wave. The phenomenon of reflection in a longitudinal pulse. The reflection and interference of incident and reflected transverse waves. The standing wave resulting from the interference between the incident and reflected wave. The antinodes and nodes of the standing wave. The vibrational speed and the propagation speed. Measuring the propagation speed of a pulse in a spring. Sound. Sound, a longitudinal mechanical wave. The propagation of sound through air and through different mechanical media. The speed of sound depends on the medium in which it propagates. The physiological qualities of sound, pitch, timbre, and intensity. Sound, Doppler effect. Low-pitched and high-pitched sounds, etc.
