Question

for resonance which must tally​

Answer 1

Hey Dear,

I assume you mean tally=equate here and resonance refers to resonance of sound waves.

● Answer -

At resonance, driving frequency of object/system tally with natural frequency.

◆ Explanation -

• Natural frequency is the frequency at which a system would oscillate if there were no driving and no damping force.
• Driving frequency here is the frequency at which object is forced to vibrate.
• Resonance is a phenomenon in which, an instrument is forced to vibrate at frequency equal to natural frequency of instrument.

Hope this helped you. Thanks for asking this question.
