Q:

Sound intensity,l, from a spherical source is a function of the distance, r, from the source of the sound. It is represented by the function I = P/4pir^2 where p is the power of the sound. Explain the behavior of the graph of l and what it means in context.

Accepted Solution

A:
Answer with Step-by-step explanation:We are given that sound intensity I form a spherical source[tex]I=\frac{P}{4\pi r^2}[/tex]Where r=Distance from the source of soundP=Power of the soundWhen r=0 then the intensity is undefined at source.When r=infinity Then , the intensity,[tex]I=\frac{P}{4\pi(\inft)^2}=0[/tex]Intensity is inversely proportional to distance r from the source of sound.It means when the distance from the source increases then the intensity decreases.When r increases and goes to infinity then the intensity approach to zero.
