Lab - Doppler Effect applied to velocity measurement

Excerpt from syllabus:
T^le S: Observation - Properties of waves
Implement an experimental approach to measure a speed using the Doppler effect.
T^le STL: Waves for observation and measurement
Doppler effect: link the frequency shift of a wave emitted by a moving source to the speed of the source.
Experimentally illustrate the principle of a Doppler effect velocimeter

Introduction:
The aim of the lab session is to experimentally find the Doppler relationship and its application to speed measurement.
