A high-Q quartz crystal exhibits series resonance at the frequency $\omega_{s}$ and parallel resonance at the frequency $\omega_{p}$. Then
- $\omega_{s}$ is very close to, but less than $\omega_{p}$
- $\omega_{s} \ll \omega_{p}$
- $\omega_{s}$ is very close to, but greater than $\omega_{p}$
- $\omega_{s} \gg \omega_{p}$
