Questions
A sound source emits sound waves in a uniform medium. If energy density is E and maximum speed of the particles of the medium is . The plot between E and is best represented by
detailed solution
Correct option is C
Energy density (E) =Iv=2π2ρn2A2vmax=ωA=2πnA⇒E∝(vmax)2i.e., graph between E and vmax will be a parabola symmetrical about E axis.Talk to our academic expert!
