The Doppler Effect: Speed Skating Finals

Summary: In this learning objective, we examine the derivation for the equations relating frequency heard by the receiver and frequencies emitted at the source for both receivers moving away and towards the source, using a Prezi. We begin with familiar equations relating period/frequency, velocity and wavelength and manipulate these to allow us to solve the problem. The setting of two moving skaters and a finishing line horn is used as context for this particular problem.
