A police car is sitting by the side of the road with a radar gun. The frequency of that gun is 24.15GHz and if the car that the officer is pointing at is moving toward the police at 75 mph.

a)What is the frequency of the radio wave that the car sees?

b) what is the frequency of the reflected radio wave that is picked up by the receiver inside the radar gun?

Please show all work! Thank you!

Doppler Effect: 1. A stationary police officer using a speed “radar detector” sends a signal with a frequency of 100,000 Hz. The speed of sound is 340 m/s. What is the wavelength of the (ultra) sound wave produced by the detector? The sound wave reflects off a vehicle moving toward the officer. How does the frequency of the reflected sound wave (as recorded by the detector) compare to the original sound wave? 2. The light waves from a distance start...

A speeder is pulling directly away and increasing his distance from a police car that is moving at 25.1 m/s with respect to the ground. The radar gun in the police car emits an electromagnetic wave with a frequency of 6.98×109 Hz. The wave reflects from the speeder's car and returns to the police car, where its frequency is measured to be 312 Hz less than the emitted frequency. Calculate the speeder's speed with respect to the ground.

A speeder is pulling directly away and increasing his distance from a police car that is moving at 29 m/s with respect to the ground. The radar gun in the police car emits an electromagnetic wave with a frequency of 7.00 109 Hz. The wave reflects from the speeder's car and returns to the police car, where its frequency is measured to be 326 Hz less than the emitted frequency. Find the speeder's speed with respect to the ground.

A police officer in a helicopter is hovering 1110 feet directly over a straight stretch of I-5 where the speed limit is 70 miles per hour. A car passes below very quickly so the officer pulls out the radar gun. At the moment of using the radar the results show that the car is 1985 feet away from the helicopter, and it is moving away from the helicopter at 95 feet per second. The helicopter officer notifies the ground patrolman...
