To determine her own speed, a skydiver carries a loud buzzer that emits a steady tone at 1820 Hz. A friend at the landing site on the ground directly below her listens to the amplified sound he receives from the buzzer. Assume that the air is calm and that the speed of sound is 343 m/s, independent of altitude (not necessarily true, but a lot easier to deal with). While the skydiver is falling at terminal speed, her friend on the ground receives waves with a frequency of 2150 Hz. (a) What is the skydiver's speed of descent? (b) Suppose the skydiver is also carrying sound-receiving equipment that is sensitive enough to detect waves reflected from the ground. What frequency does she receive?
