प्रश्न
A vibrating tuning fork, held over an air column of a given length with its one end closed, produces a loud audible sound. Name the phenomenon responsible for it and explain the observation.

उत्तर १
The phenomenon responsible for producing a loud audible sound is named resonance. The vibrating tuning fork causes the forced vibrations in the air column. For a certain length of air column, a loud sound is heard. This happens when the frequency of the air column becomes equal to the frequency of the tuning fork.
उत्तर २
Resonance describes the phenomenon. When the tuning fork frequency is 256 Hz, the loudness of a sound can be either 256 Hz or an integer multiple of 256. i.e., (256 × 1) Hz, (256 × 2) Hz, (256 × 3) Hz, ... or (256 × 5). In other words, the frequency of the tuning fork is 256 Hz, 512 Hz, 768 Hz or 1280 Hz.

The diagram above shows a wire stretched over a sonometer. Stems of two vibrating tuning forks A and Bare touched to the wooden box of the sonometer. It is observed that the paper rider (a small piece of paper folded at the centre) present on the wire flies off when the stem of vibrating tuning fork B is touched to the wooden box but the paper just vibrates when the stem of vibrating tuning fork A is touched to the wooden box.
