For this reason, the derivation of the speed of sound in a medium depends on the medium and on the state of the medium. In general, the equation for the speed of a mechanical wave in a medium depends on the square root of the restoring force, or the elastic property, divided by the inertial property,

12 wrz 2022 · Determine the speed of sound in different media. Derive the equation for the speed of sound in air. Determine the speed of sound in air for a given temperature. Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength.
17 gru 2019 · Describe the relationship between the speed of sound, its frequency, and its wavelength. Describe the effects on the speed of sound as it travels through various media. Describe the effects of temperature on the speed of sound.
What is an acoustic wave? It is essentially a pressure change. A local pressure change causes immediate fluid to compress which in turn causes additional pressure changes. This leads to the propagation of an acoustic wave. Before we derive the wave equation, let’s cover a few definitions and concepts.
Recall from Waves that the speed of a wave on a string is equal to v = √F T μ, v = F T μ, where the restoring force is the tension in the string F T F T and the linear density μ μ is the inertial property. In a fluid, the speed of sound depends on the bulk modulus and the density, v = √β ρ. v = β ρ.
Relate the characteristics of waves to properties of sound waves; Describe the speed of sound and how it changes in various media; Relate the speed of sound to frequency and wavelength of a sound wave
speed = distance/time. The faster a sound wave travels, the more distance it will cover in the same period of time. If a sound wave were observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s.
