Resonance is strong when?

Something with resonance has a deep tone or a powerful lasting effect. Resonance is the quality of being "resonant," which can mean "strong and deep in tone" or "having a lasting effect." If your voice has resonance, you might consider a profession that involves public speaking.

Answer: A resonance occurs when the net energy of the colliding subatomic particles is just enough to produce its rest mass, which the strong force then causes to disintegrate within 10-23 second.
