Question

How can a person sing into a piano and cause a piano wire to vibrate? (1 point)

O The person sings at the same frequency as the piano wire, called the beat frequency.

OThe person sings at a different frequency than the piano wire, called the beat frequency.

OThe person sings at the same frequency as the piano wire, called the resonance frequency.

OThe person sings at a different frequency than the piano wire, called the resonance frequency.

Answer 1

The person sings at a different frequency than the piano wire, called as resonance frequency. So, option d is correct.

Interference directs to a phenomenon in which two wires meet while traveling along the exact medium and they superpose to create a resulting wave that is lower, greater, or the same amplitude as each other. The soundboard is a big wooden panel that amplifies the sound of the vibrating string.

In the given scenario, a beat frequency is listened to by a player when using a tuning fork to adjust a piano wire. Thus, the piano tuner should change the strain in the wire, this decreases the frequency of the wire.

Answer 2

The person sings at the same frequency as the piano wire, called the resonance frequency.
