Answer Details

To obtain a sound note of a high pitch from a wire stretched by a constant tension, the wire must be short and thin. The pitch of a sound is determined by its frequency, which is the number of vibrations (or cycles) per second. In the case of a wire that is stretched under tension, its frequency of vibration is determined by the tension on the wire, its length, and its mass per unit length (also known as linear density). The tension on the wire remains constant, so to increase the frequency (and therefore the pitch) of the note, the wire must be made thinner or shorter. This is because a thinner wire has a lower mass per unit length, which allows it to vibrate more quickly. Similarly, a shorter wire vibrates over a shorter distance, so it can complete more vibrations per second. Therefore, to obtain a sound note of a high pitch from a wire stretched by a constant tension, the wire must be short and thin.
