A tuning fork is in resonance with a closed pipe. But the same tuning fork cannot be in resonance with an open pipe of the same length. Why ? |
| Answer» SOLUTION :For the same LENGTH of air column, and the same speed of sound, the fundamental FREQUENCY of the air column in a closed pipe half that in an open pipe. Hence, a tuning FORK in unison with the air column in a closed pipe cannot be in unison with the air column of the same length in an open pipe. | |
