Chapter 26, Problem 11A

Why do different objects make different sounds when dropped on a floor?

To determine

To Explain: The reason for different objects make different sounds when dropped on a floor.

Answer to Problem 11A

Different object has different vibration frequency and when they dropped on floor each vibrate at its natural frequency and produce different sound.

Explanation of Solution

Introduction:

The sound is a type of vibration energy. When the particles of material vibrate then the sound is produced.

Sound travels in all the three states of matter. When the particles of object are disturbed then due to vibration,the sound is produced of different frequencies. The combination of different frequency produces the special sound. Every material has different frequency of vibration which produces a special sound known as natural frequency.

When the different objects drop on floor then each object vibrate at its natural frequency and produce different sound.

Conclusion:

Thus different object has different vibration frequency and when they dropped on floor each vibrate at its natural frequency and produce different sound.
