Stationary Waves & Vibrating Strings

The frequency of a tuning fork is 256 Hz. It will not resonate with the tuning fork of frequency

Show answer and solution

Answer: (c)

Resonance (harmonics) occurs only at integer multiples of $256\text{ Hz}$ .
$256 \times 1 = 256$ , $256 \times 2 = 512$ , $256 \times 3 = 768\text{ Hz}$ .
$754/256$ is not an integer.
So the answer is (c) $754\text{ Hz}$ .
