Question

Two eagles fly directly toward one another, the first at

15.0 m/s and the second at 20.0 m/s. Both screech, the first

one emitting a frequency of 3200 Hz and the second one

emitting a frequency of 3800 Hz. What frequencies do they

receive if the speed of sound is 330 m/s?

Step 1

For the first case, the first eagle is the source and the second eagle is the observer. Both the observer and the source are moving. The variables to decribe the doppler effect equation are observed frequency *f* , actual frequency *f*_{0} , speed of sound *v*, speed of observer *v*_{0} and speed of source *v*_{s} .

Step 2

Substituting the values,

Step 3

For the second case, the second eagle is the source and the first eagle is the observer. The doppler effect equati...
