Doppler Effect notes

This section is Grade 11 wave revision: the toolkit the Doppler effect uses. You must define a pulse, a transverse pulse and a longitudinal pulse; define amplitude, **wavelength $\lambda$, frequency $f$…

This section is the Doppler effect for sound. You must state the official definition, explain why pitch rises when a source approaches and falls when it recedes, use $f_{L}=\dfrac{v\pm v_{L}}{v\pm v_{s}}f_{s}$ with the…

This section is applications of the Doppler effect: sound and ultrasound (blood-flow measurement, sonar), and red shift / blue shift of light from stars as evidence that the universe is expanding…
