Which of these is not a technique used to induce sharp resonance in resonators? Correct Answer Rigidity

Resonator achieves sharp resonance by using bulk, acoustic and piezoelectric effects. By adapting the mentioned effects, quality factor in the range of 10,000 can be achieved.

A piece of paraffin is placed in a uniform magnetic field H0. The sample contains hydrogen nuclei of mass mp, which interact only with external magnetic field. An additional oscillating magnetic field is applied to observe resonance absorption. If g1 is the g-factor of the hydrogen nucleus, the frequency at which resonance absorption takes place, is given by
Assertion (A): All the systems which exhibit overshoot in transient response will also exhibit resonance peak in frequency response. Reason (R): Large resonance peak in frequency response corresponds to a large overshoot in transient response.
There is an acoustic resonance, which echoes is the fixed resonance when it is in vibration.
