The Doppler effect - the shift in frequency/wavelength of asound source when there is relative motion between source &observer - and a Sonic Boom - a conical region of compression thatforms around the sound source when its speed exceeds the speed ofsound in the medium of the source, and results in an observed\"boom\" when part of the cone passes the observer's location - aretwo interesting, common, as well as connected phenomena seen thisweek.
For the Doppler effect, give and discuss briefly twoapplications, see if you can do one stemming from nature and onetechnology (man-made).
For the sonic boom, see if you can give two occurrences stemmingfrom nature and two from man-made situations.
