Chapter 10, Problem 45R

To determine

To explain: how a room which absorbs all sound waves, can be used to study how bats find their food.

Explanation of Solution

Introduction:

Bats use the process of echolocation to find their foods where they send sound wave and locate their prey.

If a room absorbs all sound waves, then there will be fewer amounts of echo. Without echoes the bats find it difficult to locate their food and shall bump into objects. They typically rely on the reflection of sound waves to locate objects of prey.

Conclusion:

Thus, a room which absorbs all sound waves, can be used to study how bats find their food.
