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

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

A sonometer wire is subjected to a certain tension. If the tension is increased four times and the length of wire is reduced to half the original value, how is frequency of vibrations altered ?

The frequency of transverse vibration on a stretched string is 150 Hz. If the tension is increases four times and length is reduced to one fourth of its original value, the frequency of vibration will be
