A traffic official, hiding in the bushes, is using a radar speed gun to check the speeds of motor vehicles driving on the highway. The radar gun signals a frequency of 9 MHz. In the case where the motor vehicle is approaching the traffic official at 96 km/h determine the following:

A. The frequency of the signal as detected by the motor vehicle. Units: MHz

B. The frequency detected by the radar speed gun for the signal reflected back to it by the motor vehicle. Units: Hz

Answer #1

V. = 96 Kunth = 96X1000 3600 = 26.67 APP 8 happy 3x10 + 26:67 (9 Mitz) 3x108 9.00000081 MHZ 13x10 9.00000081 fopp 3x108-26:67

    A TV station has a weather radar which is monitoring an approaching thunderstorm. The radar emits radio waves at a frequency of 2900 MHz . The thunderstorm line is approaching the radar installation at 45.0 km/h Radio waves are reflected from the water drops in the thunderstorms, and the reflected waves are detected back at the installation. As measured by the receiver at the installation, is the frequency of these reflected waves greater or less than 2900 MHz ? By...

    Police radar determines the speed of motor vehicles using the same Doppler-shift technique employed for ultrasound in medical diagnostics. Beats are produced by mixing the double Doppler-shifted echo with the original frequency. If 2.25 ✕ 1010 Hz microwaves are used and a beat frequency of 2,400 Hz is produced, what is the speed (in m/s) of the vehicle? (Assume the same Doppler-shift formulas are valid with the speed of sound replaced by the speed of light.)
