Question

21 multiple choice 2 points if you start with a note with a frequency of 140 hz, what frequency is two octaves higher than this frequency?

Explanation:

An octave higher means doubling the frequency.

Step2: Calculate the frequency after first octave

After one octave, the frequency is \(140\times2 = 280\) Hz.

Step3: Calculate the frequency after second octave

After the second octave, the frequency is \(280\times2=560\) Hz.
