WebWe propose a method to measure the speed of sound in air using a motion detector. The experiment is based on the principle of a motion detector used to measure distances. This device measures the time of flight of alternating ultrasonic waves between the observer and the target. By assuming a fixed speed of sound, the time of flight can be converted into … WebBack in 1965, the U.S. Federal Aviation Agency [The FAA] developed a simple estimation of Tc to be used with the Rational Method.
