1.
A source of 400 Hz moves toward a stationary observer at 34 m s−1 (v = 340 m s−1). The observed frequency is
360 Hz
440 Hz
400 Hz
444 Hz
2.
A source of 400 Hz moves away at 34 m s−1. The observed frequency is
360 Hz
440 Hz
364 Hz
356 Hz
3.
An observer moves toward a stationary 500 Hz source at 17 m s−1 (v = 340 m s−1). They hear
475 Hz
525 Hz
526 Hz
500 Hz
4.
In the moving-source equation for approach, the denominator is
v − us
v + us
us − v
v
5.
Sound reflects from an approaching vehicle. The shift is approximately
fu/v
fu/2v
u/fv
2fu/v
6.
A source emits at 600 Hz and is heard at 540 Hz while moving away. The speed of the source, relative to v, is
us = v/10
us = v/8
us = v/9
us = v/6
