Question
A bat flying toward a wall cmits a chirp at $40 \mathrm{kHz}$. Is the frequency of the echo received by the bat greater than, less than, or equal to $40 \mathrm{kHz}$ ?
Step 1
A bat is flying toward a wall and emits a chirp at a frequency of 40 kHz. The bat will receive an echo of this chirp after it reflects off the wall. Show more…

A bat flying toward a wall emits a chirp at $40 \mathrm{kHz}$. Is the frequency of the echo received by the bat greater than, less than, or equal to $40 \mathrm{kHz} ?$
A bat flies toward a wall, emitting a steady sound of frequency 1.70 $\mathrm{kHz}$ . This bat hears its own sound plus the sound reflected by the wall. How fast should the bat fly in order to hear a beat frequency of 10.0 $\mathrm{Hz}$ ?
A bat chirps as it flies toward a wall. Is the frequency of the echoed chirps it receives higher than, lower than, or the same as the emitted ones?
