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 (v_ max ). The plot between (E ) and (v_ max ) is best represented by

Correct answer

2

Step-by-step solution

Energy density ((E)=2 ^2 r^2 n^2 A^2 ) (v_ = A=2 n A E (v_ )^2 ) i.e. graph between (E ) and (v_ ) will be a parabola symmetrical about (E )-axis.
