Question
The bells of a temple are big in size. Why?
✓
Answer
According to the study of bells (called campanology), larger bells provide less resonant frequency.
For a sound wave to travel long distances, it is essential that the frequency of the sound is less.
Also, it is observed that thicker the body of a bell, richer is the quality of sound.
This is the reason the bells of a temple are big in size.
