Doppler Effect Investigatory Project

[JGL]

Can someone give me an idea on our Investigatory project about Doppler Effect...?

Our project shouldn't be amounting in an expensive one. I am only 4th year high school student and so confuse what project will i make... Please Help me guys.

Thanks in Advance Guys!

hello to everyone there,i am also very problematic about our INVESTIGATORY PROJECT bacause i donnot have enough information about it... so i am looking somebody who has a knowledge about investigatory to help me in our projecc...please help us... our topic is to do a simple device that can be use in our school...i am llooking forward for an urgent reply for my request...thank you...

Could you use some fast Fourier transform (fft) software to measure the doppler pitch change from a moving vehicle? See

Here is a nice link for you: "Hacking the Hot Wheels Radar Gun"
http://www.edparadis.com/radar/

Note that the micro controller on that device can easily be reprogrammed using the open source software tools. It is also very cheap, only $30 :)

In post #4, I should have added "measuring the pitch change of a horn in a moving vehicle and comparing it to a radar gun."

wow they look complicated...
they need a small device...

the easiest experiment i can think of is having a dish of water moving something up and down which make a wave pattern, now move the source (the up and down thing creating the wave) away and towards a marked side of the dish and you will see the wavelength of the waves change as your move the source (the up and down thing creating the wave)
the faster the source and the speed your moving the source the easier it is the see the effect

what I've just described above is in this video

(ignore the first bit when she's in the bath it's NOT R rated)
all you basically have 2 do is replace the duck with something electrical and call it a devise lol...
