Problem 6: Radar gun A police car is at rest parallel to the highway and measures the speed of cars. It sends the signal with a frequency of 1200 Hz, it bounces off the moving car (it is traveling toward or away from the signal emitted) and the radar gun measures the frequency of the signal received. For one car suspected of speeding the received frequency was 1100 Hz. The speed of sound is approximately 350 m/s (note our radar...

A traffic cop sends a radar signal of 2.0 ×10^9 Hz towards a car approaching with a speed of 120 km/s. Find the difference between the frequency of the light emitted by the radar, and the frequency reaching the speeding car. - 180 Hz - 222 Hz - 330 Hz - 460 Hz

Problem 4: Radar gun Police car is at rest parallel to the highway and measures the speed of cars. It sends the signal of the frequency 1500 Hz which bounces off the moving car and the radar gun measures the frequency of the signal received. For one car suspected of a speed limit violation the received frequency by the radar gun was 1250 Hz. The speed of the sound in the air is approximately 350 m/s a) How fast was...

A police radar gun operates at an emitted frequency of 10 GHz (10 x 109 Hz). The police officer aims his radar toward a speeding car moving directly away from him at v = 0.2c. The signal reflects off the car and travels back to the police officer where he detects it. What frequency does he detect? Instead the police officer aims the radar at an airplane flying directly overhead at an altitude of 10,000 m with v=0.2c in a...

A police car uses a radar gun to measure the velocity of a car and find out if it is speeding. The most common radar gun mounted inside the squad car window or dashboard and lies in the X band frequencies of microwaves of 10.50-10.55 GHz. A handheld version of this radar gun utilizes the K band frequencies between 24.05-24.25 GHz. A handheld radar (source of waves) with a frequency of 24.13 GHz is directed to car moving at 61...
