Chapter 15.2, Problem 18PP

To determine

To Explain: The tube from which a tuba is made is much longer than that of a comet.

Explanation of Solution

Introduction:

Resonance is defined as the process of increasing the amplitude which takes place when the periodically applied force frequency is matched with the natural frequency on which it acts.

Frequency is defined as the phenomena of repeating an motion per unit time. It is reciprocal of the time period of the wave. Its SI unit is Hertz.

As it is known that the tuba makes higher pitch and louder sound comparatively to the cornet, that’s why the tuba is made from the longer tube. Longer the tube, higher will be the air column. The vibrating air frequency that will be set into the resonance will be determined by the length of the air column. As the length of the tube increased, length of the air column also increased due to which a sound of high pitch is produced.

Conclusion:

Tube from which a tuba is made much longer than that of a comet so that it can produce the sound of high pitch.
