two of the same instrument playing notes at slightly different frequencies
How can a person sing into a piano and cause a piano wire to vibrate?(1 point) Responses The person sings at the same frequency as the piano wire, called the beat frequency. The person sings at the same frequency as the piano wire, called the beat frequency. The person sings at a different frequency than the piano wire, called the beat frequency. The person sings at a different frequency than the piano wire, called the beat frequency. The person sings at a different frequency than the piano wire, called the resonance frequency. The person sings at a different frequency than the piano wire, called the resonance frequency. The person sings at the same frequency as the piano wire, called the resonance frequency.
The person sings at the same frequency as the piano wire, called the resonance frequency.
The wires in a piano vibrate, but fractions of the wire also vibrate at different frequencies than the whole wire. What is the term for the softer notes produced by these different frequencies?(1 point) Responses harmonics harmonics resonance resonance interference interference pitch
