Question 16
A piano makes sound when its strings vibrate. Successive A notes are an octave apart. The frequencies of the A notes are shown in the table.
| Note | Frequency / Hz |
|---|---:|
| A₀ | 27.5 |
| A₁ | 55.0 |
| A₂ | 110 |
| A₃ | 220 |
| A₄ | 440 |
The piano can also produce the notes A₅, A₆ and A₇. Use the trend in the table to predict the frequencies of these three notes.
