A radio acoustic sounding system (RASS) instrument uses 404-MHz radio waves (wavelength = 0.743 m). (a) What is the wavelength of the sound waves used to measure air temperature? ë = ___ m (b) If the Doppler shift of the radio wave reflected from a region several hundred meters above the ground indicates a sound speed of 330 m/s, what is the air temperature? T = ___°K
