Experiment - Experiments on the Doppler Effect
Have you heard an ambulance go by recently?
Remember how the siren's pitch changed as the vehicle raced towards, then away from you?
First the pitch became higher, then lower.
Originally discovered by the Austrian mathematician and physicist, Christian Doppler (1803-53), this change in pitch results from a shift in the frequency of the sound waves.
This programme is another Jack Smith classic from Granada TV.
More pointy pencils and this time a man with a beard carrying out useful bench experiments.
This programme is again a perfect example as to the difference in pace at which the information was portrayed compared to modern presentations.
