Concept explainers
The frequency of the wave detected by the bat.
Answer to Problem 86GP
Explanation of Solution
Given:
The velocity of bat,
The velocity of moth,
The frequency of bat,
Formula used:
The apparent frequency is calculated in two cases.
In the first case, the emitted sound with the bat as a source and moth is an observer.
Case 1:
In the second case, the reflected sound of moth is the source and bat is the observer.
Case 2:
Here,
Calculation:
Substitute the given values:
Conclusion:
The frequency of the wave detected by the bat is
