Question

If a pitch vibrates at 880 cycles, the octave below would vibrate at ____ cycles. 220 440 660 1760

Answer 1

If a pitch vibrates at 880 cycles, the octave below would vibrate at 440 cycles.

Step-by-step explanation:

Pitch of sound is defined as relative highest and the lowest point of sound. The pitch is dependent on frequency of vibration.

Octave is defined as a tone which is formed due to merging of two different tone. The resultant tone is merged so well that it sound like a single tone.

Thus, Number cycle in octave =
`(number of cycles in a pitch)/(2)`

Number cycle in octave =
`(880)/(2)`

Number cycle in octave = 440

Thus, If a pitch vibrates at 880 cycles, the octave below would vibrate at 440 cycles.
