What is the fractional change in tension in a sonometer wire of constant length to produce a note one octave lower than the previous note?

What is the percentage change in the tension necessary in a sonometer of fixed length to produce a note one octave lower (half of original frequency) than before?

What is the percentage change in the tension necessary in a somometer of fixed length to produce a note one octave lower (half of original frequency) than before?

5 beats / second are heared when a tuning fork is sounded with a sonometer wire under tension when the length of the sonometer wire is either 0.95 m or 1 The frequency of the fork will be :

Two identical sonometer wires have a fundamental frequency of 500 Hz when kept under the same tension . The percentage change in tension of one of the wires that would cause an occurrence of 5 beats//s , when both wires vibrate together is

Two identical sonometer wires have a fundamental frequency of 500 Hz when kept under the same tension . The percentage change in tension of one of the wires that would cause an occurrence of 5 beats//s , when both wires vibrate together is

A wire of uniform cross - section is suspended vertically from a fixed point , with a load attached at the lower end . Calculate the fractional change in frequency of the wire due to rise in temperature by t^(@) C . The coefficient of expansion of the wire is alpha .

Two identical piano wires have a fundamental frequency of 600 cycle per second when kept under the same tension. What fractional increase in the tension of one wire will lead to the occurrence of 6 beats per second when both wires vibrate simultaneously?

Two identical stretched wires have a fundamental frequency 200 vibrations per second when kept under the same tension. What percentage increase in tension in one wire will produce 4 beats per second when both wire vibrates together (AT < < T)

Two tuning forks produce 5 beats when sounded together. A is in unison with 40 cm length of a sonometer wire under a constant tension and B is in unison with the same wire of length 40.5 cm under the same tension. Calculate fundamental frequency of the forks.

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
