  • Sorry. The relative frequency will decrease :p

  • @theonlymoak,

    In that case it will depend on whether the police and the car being chased are in motion or not. If the car being chased moves faster than the police, then we should take the case where the source is stationary and the observer is moving, in that case, the relative frequency of the pulse emitted will increase. With this, the police will be able to find the relative position of the thief(chased car) by finding the distance.

  • @TheOnlyMoak haha I literally had this question on my final exam a couple of weeks ago. I wish I knew the answer to this question, of course.

  • so i have a question, hopefully someone can answer it. when police use radar guns they are applying the doppler effect. so when the wave hits the car what exactly happens to it? does it now take on the velocity of the car? without changing the velocity of the wave?

  • great video.

    what software are you using to make it?

  • You saved me from my Physics Periodic Test. TNX \m/

  • wow much better explanation than my teacher did

    thanks a lot

  • Thank you so much :D this makes no sense in my textbook haha , but now I get it

  • Nice video, thanks!

  • Great video!
