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 speeds of a pulse in a spring under different tensions. Mechanical waves. Wave pulse, longitudinal pulse and transverse pulse. Measuring the propagation time of the pulse along the spring with length L1. Measuring the propagation time of the pulse along the extended spring with length L2. Measuring the propagation time of the pulse along the extended spring with length L3. Sound. Sound, a longitudinal mechanical wave. What is meant by a tuning fork. Some applications of the tuning fork. The propagation of sound through different mechanical media. The speed of sound depends on the medium in which it propagates. The propagation of sound through a solid. The propagation of sound through a liquid. The physiological qualities of sound: pitch, timbre, and intensity. Sound, phenomena of interference, resonance, and beat. Sound, the Doppler effect. Low-pitched and high-pitched sounds. Measuring the speed of sound in air. Measuring and determining the average speed of sound in air. Calculating the speed of sound in air, considering ambient temperature, etc.
