The vertical asymptote is r = 0. The intensity is undefined at the source. The horizontal asymptote is I = 0. As the distance from the source increases, the intensity goes to zero. The intensity decreases as the distance increases.

Answer with Step-by-step explanation:

We are given that sound intensity I form a spherical source

$I=\frac{P}{4\pi r^2}$

Where r=Distance from the source of sound

P=Power of the sound

When r=0 then the intensity is undefined at source.

When r=infinity

Then , the intensity, $I=\frac{P}{4\pi(\inft)^2}=0$

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.
