In order to double the frequency of the fundamental note emitted by a streched string, the length is reduced to `3/4th` of the original length and the tension is chaged. The factor by which the tension is to be changed is

In order to double the frequnecy of the fundamental note emitted by a stratched string the length is reduced to 3/4 th of the original length and the tension is changed. The factor by which the tension is to be changed is

In order to double the frequency of the fundamental note emitted by a stretched string, the length is reduced to (3)/(4) th of the original length and the tension is changed. The factor by which the tension is to be changed is

If the tension of the wire is increased four times and its length reduced to half the original length the frequency of vibration

Discuss, in which of the cases given below, the pitch of the fundamental tone emitted from a taut string may increase : (i) when length of the string in increased (ii) when length of the string is decreased (iii) when tension in the string is increased (iv) when tension in the string is decreased

A Sonometer wire emits a tone of frequency 150 Hz . Find out the frequency of the fundamental tone emitted by the wire if the tension is increased in the ratio 9 : 16 and the length is doubled .
