[AI-generated answer — Explain Bot]

To make a piano wire vibrate by singing into a piano, the person needs to sing at the same frequency as the resonance frequency of the piano wire. This is called the resonance frequency. When the person sings at this frequency, it causes the air inside the piano to vibrate and transfer the vibrations to the piano's soundboard. The soundboard then transfers these vibrations to the piano strings, specifically the string that shares the same resonance frequency with the person's voice. As a result, the piano wire starts to vibrate and produce sound.
