Police use radar guns and the Doppler effect to catch speeders. The figure below illustrates a moving car approaching a stationary police car. A radar gun emits an electromagnetic wave that reflects from the oncoming car. The reflected wave returns to the police car with a frequency (measured by on-board equipment) that is different from the emitted frequency. One such radar gun emits a wave whose frequency is 8.0 x 10° Hz. When the speed of the car is 21.0 m/s and the approach is essentially head-on, what is the difference between the frequency of the wave returning to the police car and that emitted by the radar gun?

Electromagnetic waves are a form of radiation that propagates through space and the atmosphere without the need for a material medium. They consist of oscillating electric and magnetic fields that alternate perpendicular to each other and to the direction of propagation. Electromagnetic waves emitted by transmission antennas, such as radio antennas, travel through the atmosphere at the speed of light and can be captured by receiving devices, such as radios, televisions and other electronic devices, allowing distance communication and the transmission of information. Statement: Radio station antennas emit electromagnetic waves that propagate in the atmosphere at a speed of around 3.0x10^5 km/s and with frequencies that vary from one station to another. If a radio emits a wave of frequency 101.5 MHz then its wavelength is approximately equal to: Question options: a) 0.31 m b) 5.15m c) 3.63m d) 1.52 m e) 2.96 m
