Two microphones are placed 50 m apart along a straight line. A small firecracker is ignited next to microphone A. Microphone B detects the sound 0.145 s after microphone A. The speed of sound in air is given by v=331m/s+0.60T, where T is the air temperature in °C.
(a) Determine the air temperature.
(b) For this temperature, calculate the wavelength of a 500 Hz tone emitted by a loudspeaker.
a. Determine the air temperature.
b. Calculate the wavelength of a 500 Hz tone at this temperature.
