Doppler Effect for High School Physics

Post by fionakv » Mon Apr 06, 2015 8:13 am

I would like to do the following Doppler Effect investigation with my class, but am not sure of how to use Audacity to analyse the results...has anyone done this and could send me some step-by-step instructions?
Thanks, Fiona.
