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
