A stationary point source of sound emits sound uniformly in all directions in a non absorbing medium. Two points 
and 
are at a distance of 
and 
respectively from the source. The ratio of amplitudes of the waves at 
and 
is
A
B
C
D
.
Text Solution
Verified by ExpertsThe correct answer is:
D
For an isotropic point source of power 
, intensity 
at a distance 
from it will be
Since power 
remains the same,
, where 
is the amplitude of a wave
.
