Question
Differentiate between the forced and resonant vibrations.
✓
Answer
| Forced Vibrations | Resonant vibrations |
| These are vibrations of a body under an external periodic force of frequency different than the natural frequency of the body. | These are vibrations of a body under an external periodic force of frequency exactly equal to the natural frequency of the body. |
| The amplitude of the vibration is usually small. | The amplitude of vibration is very large. |

A rifle shot is fired in a valley between two parallel walls. The echo from one wall is heard in 3 s and the echo from the other wall is heard 3 s later. If the velocity of sound at 00 c is $330 ms^{-1}$ and the temperature in the valley is 100 c , calculate the width of the valley. For every 10 c rise in temperature, the velocity of sound increase by $0.61 ms^{-1}$.
