alright. disregarding the doppler shift issue. can we return to my original question. what equation does the radar gun use calculate the speed of the vehicle?
it uses the change in frequency right?
generally does it? alright
the wave emitted from a stationary radar gun to a moving car does experience two Doppler shifts.
1. when the source (radar gun) is stationary and the observer (car) is moving. 'A doppler effect also occurs when an observer moves towards a source, but here the...
there are two doppler shifts, the first occurs when the radar first emits a wave, the source is stationary and the observer is moving. the second occurs when the wave is reflected back, the source is moving and the observer is stationary.
neither of these answer my question.

Radar Guns are used to measure the speed of a moving object.
The wave it emits experiences two Doppler shifts.
How does the radar gun then use the difference in frequency of the initial wave it emits and the frequency of the final wave it receives to calculate the speed of the object...
Alright. Physics Internal. I am investigating a physics principle applied into a practical way. Radar Guns and the Doppler Effect. Now the issue is, firstly, that I have encountered two equations to give me the perceived frequency of a wave with a moving observer and stationary source. I am not...
