Question

If the length of a vibrating string is increased, its pitch _________.

Answer 1

1. The instruments in which sound is produced by the vibrations in stretched metal wires are called string instruments e.g. sitar, violin, etc.
2. The frequency of vibration depends on the length, thickness, and tightness of the strings.
3. The frequency is inversely proportional to the length of the string.
4. A short string produces a high-frequency sound than a long string.
5. Therefore, if the length of a vibrating string is increased, its pitch decreases.
