Question

if following illustration dipicts acoustic pressure vs. distance in a medium in which a sound wave is present. What sound parameter is measured by athe lenght of the bar labeled A in the following illustration.

Answer 1

Answer:

Wave length is measured by parameter A

Explanation:

Considering the illustration attached in Fig below.

Given that a sound wave is present, acoustic pressure is plotted along y-axis and x-axis shows the distance. A to be measured is labeled along x-axis and the parameter it measures would be wave length of sound wave.
