A: resonance

B: crystal defects:

C: Q factor

D: critical damping

Answer 1

the shattering of a crystal glass by an intense sound is an example of Resonance.

Essentially, the glass breaks because the sound is at the right frequency. Every object has a natural frequency, at which it prefers to vibrate. This is called the Resonant frequency.At that frequency, the vibrations in the glass will be much more intense than at any other frequency. If they are intense enough, the glass will break. It does not need to be a very high frequency, just the right, resonant, frequency for that glass.

Thank you?
