For long range communication an elephant uses a low frequency rumble that is undetectable to human ears. One elephant can pick up another elephant's call from a distance of 10 km. The frequency of this rumble is about 13 Hz. How fast does the rumble travel?

1 answer

sound propagation is directly proportional to the medium it travels. factors contribute to propagation are altitude, humidity,& temperature of the gas, like air. speed of sound is determined by air itself not on amplitude, frequency, or wavelenght.Formula: V (velocity)= meters/second, ft/second, or mph + T (temperature)in F or C.
