Here, the angle formed between the path of the wave. Wavelength The distance between two consecutive points in a longitudinal wave is known as wavelength. ... light waves enter a prism and slow down due to the change in medium; this causes the waves to bend (refract) as they move through new medium. Dancing Sprinkles. Compression. A longitudinal wave is a mechanical wave in which medium particles' vibration is the same direction as the propagating wave. The crest of a wave is the highest point that it reaches, while the trough of the wave is the lowest point. A rarefaction wave is also called a relief wave, an unloading wave, and a Taylor wave. The distance between the particles in the rarefaction is greater than the normal distance. In a rarefaction, the space in which particles can move is high and hence they are at low pressure. The amplitude is the distance from the equilibrium position of the medium to a compression or a rarefaction. RarefactionContents.
