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.
2 answers:
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
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,
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.
