Discuss the mode of vibration of air columns in a closed pipe and hence define the fundamental frequency of vibration.

Discuss modes of vibration of air column in a closed pipe.

The frequency of vibration of string can be increased by

The tension in a sonometer wire is increased by a factor of four . The fundamental frequency of vibration changes by a factor of

A wire under tension vibrates with a fundamental frequency of 600 Hz.If the length of the wire is doubled,the radius is halved and the wire is made to vibrate under one-ninth the tension.Then the fundamental frequency will become

In a closed organ pipe, the fundamental frequency is 50 Hz. The frequency of second overtone is
