A. L = V/F = 343/258 = 1.33 m.
B. F = ((Vs+Vr)/(Vs-Vg))*Fo = 258 Hz
((343+0)/(343-12.6))*Fo = 258
(343/330.4) * Fo = 258
1.0381Fo = 258
Fo = 248.5 Hz=Initial Freq. of the goose
F = ((343-0)/(343+12.6))*248.5
F = (343/355.6) * 248.5 = 239.7 Hz When
flying away.
In this section assume the sound speed in air is 343 m/s.
A goose flying toward you at 12.6m/s emits a squawk, which you hear at 258Hz .
A)Find the wavelength of the sound you hear
B)Find the wavelength of the sound you hear if the goose emits the same squawk while flying away at the same speed?
