Question

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 the amplitude of the pressure fluctuations is larger. In addition to the larger amplitude, what distinguishes the second sound from the first one?(A) It is perceived as higher in pitch(B) It is perceived as louder(C) It has a higher amplitude(D) It has a longer wavelength

Answer 1

option B

Step-by-step explanation:

The correct answer is option B

The pitch of a sound depends upon the frequency of the sound wave.

Higher the frequency of the sound higher will be the pitch of the sound and lower the frequency if the sound lower will be the pitch of the sound.

Where as the amplitude is related to the loudness

if the amplitude of the second wave is large then the second sound wave will be louder than the first one.
