A truck traveling east at 21 m/s sounds a 1200 Hz horn. Find the wavelength of the sound heard by a stationary listener placed east of the truck? (The speed of sound is 340 m/s)
If you move at 11 m/s toward a 2300 Hertz source that is moving toward you with a ground speed of 36 m/s, compute what frequency do you hear?(The speed of sound is 340 m/s)
