A car moving at 150 km per hour is approaching a stationary police car whose radar speed detector operates at a frequency of 15 GHz. What frequency change is found by the speed detector?​

Answer»

Explanation:

Vr=150km/h * 5/18

Vr = 41.66m/s.

F = ((V-Vr)/(V+Vs))*Fo.

F=((343-41.66) / (343+0))*15 = 13.178 HZ

CHANGE = 15 - 13.178 = 1.822 GHz.
