How do we determine how far away sounds are

WebThe relationship of the speed of sound vw, v w, its frequency f, f, and its wavelength λ λ is given by. vw = f λ, v w = f λ, which is the same relationship given for all waves. In air, the speed of sound is related to air temperature T T by. vw … 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.

WebFor simplicity of calculation, let's say it's 600 mph (the exact speed is determined by the air's pressure, temperature and humidity). Imagine that the car is standing still, it is exactly 1 mile away from you and it toots its horn for exactly one minute. The sound waves from the horn will propagate from the car toward you at a rate of 600 mph. http://pressbooks-dev.oer.hawaii.edu/collegephysics/chapter/17-2-speed-of-sound-frequency-and-wavelength/
