2.

a) Why does the Doppler effect differ in the case where the source moves to the fixed observer, from the one in which the observer moves to a fixed source?

b) Explain what the resonance effect consists of. Give an example.

Please answer the questions with maths! and explain physically, thank you in advance !

The Doppler effect - the shift in frequency/wavelength of a sound source when there is relative motion between source & observer - and a Sonic Boom - a conical region of compression that forms around the sound source when its speed exceeds the speed of sound in the medium of the source, and results in an observed "boom" when part of the cone passes the observer's location - are two interesting, common, as well as connected phenomena seen this week....

1.) The Doppler effect takes on two forms: blueshift and redshift. Where do these names come from? How might it be possible to explain their sig- nificance in terms of an approaching or receding sourceof water waves? Is the water situation identical to the light situation? Why or why not? 2.) If a light source moves away from you, you detect a redshift; if a light source moves toward you, you detect a blueshift. If the source is stationary, but...
