The fundamental frequency of a sonometer wire increases by 9 Hz when its tension is increased by 69%, with the length remaining unchanged. We need to determine the original frequency of the wire.

The frequency of vibration of a stretched string is determined by the formula:

$$ \nu = \frac{1}{2} \sqrt{\frac{T}{m}} $$

Where:
