A perceived increase in the volume of sound is best explained by ________.

A. an increase in the height of the sound wave
B. an increase in the width of the sound wave
C. a combination of multiple sound waves
D. a decrease in the width of the sound wave

Respuesta :

Answer:

A. an increase in the height of the sound wave

Explanation:

Volume of the sound is measured by its intensity

So here we know that

intensity is directly depends on the square of the amplitude of the sound wave

so here as intensity depends on the loudness of the sound given as

[tex]L = 10 Log(\frac{I}{I_o})[/tex]

so here as the loudness of sound will increase then the intensity will increase and hence the amplitude of the sound will also increase

So correct answer will be

A. an increase in the height of the sound wave
