Question 10
Police radar speed guns basically work by reflecting electromagnetic waves off the car's surface. Suppose you want to
drive real fast on the motorway and somehow you have tracked exactly the frequency of police speed radar. The
frequency of the police speed radar is f 1238 Hz. Find its wavelength. Hint c = 3 x 10% No need to include the unit.
