People with very good pitch discrimination can very quickly determine what note they are listening to. The note on the musical scale called C₆ (two octaves above middle C) has a frequency of 1050 Hz. Some trained musicians can identify this note after hearing only 12 cycles of the wave.

How much time does this correspond to?

Darcy · Answer 1

= 11ms

Explanation:

We have,

1050Hz = 1050cycles / s

Divide the number of cycle by the number of cycle per seconds

we have,

no. of cycles / frequency = Time

so the solution will be:

12 cycles / 1050 Hz = 0.0114 seconds

Convert seconds into milliseconds by multiplying it by 1000 which is

0.0114 seconds * 1000

= 11.43ms

≅ 11m/s
