Chapter 15, Problem 12P

To determine

To find comparison of the average energy densities in between sound $\text{A}$ and $\text{B}$ at given condition.

(a) The average energy density of $\text{A}$ is twice the average energy density of $\text{B}$ .

(b) The average energy density of $\text{A}$ is four times the average energy density of $\text{B}$

(c) The average energy density of $\text{A}$ is $\text{16}$ times the average energy density of $\text{B}$ .

(d) You cannot compare the average energy densities from the data given.
