Speed of wave in vacuum
WebWhile not negligible, this is not a strong dependence. At 0 °C, the speed of sound is 331 m/s, whereas at 20.0 °C, it is 343 m/s, less than a 4 % increase. Figure 17.6 shows how a bat uses the speed of sound to sense distances. Figure 17.6 A bat uses sound echoes to find its way about and to catch prey. In a region with no charges (ρ = 0) and no currents (J = 0), such as in a vacuum, Maxwell's equations reduce to: Taking the curl (∇×) of the curl equations, and using the curl of the curl identity we obtain The quantity has the dimension of (time/length) . Defining , the equations above have the form of the standard wave equations
