A certain sound is recorded by a microphone. The same microphone then detects a second sound, which is identical to the first one except that it has twice the frequency. In addition to the higher frequency, what distinguishes the second sound from the first one?

A. It is perceived as higher in pitchB. It is perceived as louderC. It has a higher amplitudeD. It has a longer wavelength

Madden Conrad · Answer 1

The answer is: A. It is perceived as higher in pitch

Explanation:

The pitch in a sound is dependent on the frequency of that wave. a high frequency wave would have a high pitch and a low frequency wave would have a low pitch sound. If you have twice the frequency it would have a much higher tone than the first one. In conclusion, it is perceived as a higher tone.
