A tuning fork used in an acoustic calibration experiment vibrates freely with a natural frequency of 125 Hz.
Which statement is correct about this oscillator?
The natural period of the vibrating tuning fork is 8.0 ms8.0\text{ ms}8.0 ms.
The period of the freely vibrating tuning fork increases as its amplitude decays.
The tuning fork will resonate with maximum amplitude when driven by an external source of frequency 250 Hz250\text{ Hz}250 Hz.
The angular frequency of the freely vibrating tuning fork is approximately 125 rad s−1125\text{ rad s}^{-1}125 rad s−1.
