    A wave is a form of disturbance that travels through a material medium due to the repeated motion of the particles of the medium about their mean positions without any actual transportation of matter. Simply put, a wave can be thought of as a periodic oscillation that travels through space-time, accompanied by a transfer of energy.
    Air can be viewed as being composed of layers analogous to such coils, with a sound wave propagating as layers of air “push” and “pull” at one another much like the compression moving down the spring. A sound wave thus consists of alternating compressions and rarefactions, or regions of high pressure and low pressure, moving at a certain speed.
    Wavelength is the distance between any point on a wave and the corresponding point on the next wave. Technically, sound is defined as a mechanical disturbance traveling through an elastic medium — a material that tends to return to its original condition after being deformed. The medium doesn't have to be air.
    Figure 1C is another representation of the sound wave illustrated in Figure 1B. As represented by the sinusoidal curve, the pressure variation in a sound wave repeats itself in space over a specific distance. This distance is known as the wavelength of the sound, usually measured in metres and represented by λ.
