A piano wire weighing and having a length of emits a fundamental frequency corresponding to the “Middle C” . Find the tension in the wire.
To find the tension in the wire:
Step 1. Given:
Length of the piano wire,
Mass of the wire
Fundamental frequency
Let the tension in the wire be
Step 2. Linear mass density,
Step 3. Fundamental frequency,
We know that fundamental frequency,
Hence, the tension in the piano wire is .
