Consider a Doppler radar system that monitors the wind speed of a tornado by measuring the shift in frequency of radio waves reflected from water droplets or other particles in the air. If this wind speed is 45 m/s (about 100 mi/h) and the transmitted radio wave has a frequency of 1.0 MHz (106 Hz), what is the frequency of the reflected wave? Assume the droplets reflecting the wave signal are moving toward the antenna. Hint: Take all given numbers as “exact” and keep a large number of significant figures in your final calculation.
