Question

A police officer's radar gun emits radio waves at a frequency of 11.1 GHz. Assume that the cars are both headed directly away from the stationary officer. Use $c = 3.000 \times 10^8 m/s$ for the speed of light and 1 mph = 0.44704 m/s. What is the magnitude $\Delta f$ of the difference in the frequencies reflected back to the radar gun by a car traveling at the 80 mph speed limit and a car travelling 1 mph faster? $\Delta f = \text{____} Hz$

Step 1

The plus sign in the denominator is used when the source is moving towards the receiver, and the minus sign is used when the source is moving away from the receiver. Show more…
