Question

with which of the following frequencies dose a tuning fork of frequency 128 Hz resonate?

196 Hz,216 Hz,256 Hz,314 Hz,512 Hz.

Answer 1

• Fundamental frequency of the tuning fork, n = 128 Hz
• Second harmonic of the tuning fork = 2n = 256 Hz

Hence, the resonating frequency close to the frequency of tuning fork = 256 Hz
