Question

Intensities of a sound as observed at distances 5 m and 10 m from its source are in the ratio

Answer 1

Intensity of a point source of sound at a point is given by ,

I=Power/4πr

2

,

where , r= distance of point from the source of sound ,

it is clear that ,

I∝1/r

2

Answer 2

Step-by-step explanation:

as we know that intensity is inversely square proportional to distance

so,(I2/I1)=(10/5)^2=4/1

4:1 is your answer
