In a sonometer experiment resonance is obtained when the experiment wire has a length of 21 CM between the bridges and the vibrations are excited by A tuning fork of frequency 256 Hertz. If A tuning fork of frequency 384 hertz is used what should be the length of the experimental wire to get the resonance.

Dear Student
Here, l1 =21 cm, f1 = 256 Hz
l2 = ? , f2 = 384 Hz
As
l1 * f1 = l2 * f2
l2 = 256 * 21/384 = 14 cm
