Vedclass · Answer

(B) For the formation of stationary waves,it is necessary that the medium should be bounded. When a wave propagates in a bounded medium,it reflects at the boundary,producing a wave of the same frequency and amplitude travelling in the opposite direction. The superposition of these two waves results in a stationary wave. Thus,the $Assertion$ is correct.In stationary waves,there are specific points in the medium where the displacement is always zero. These points are called nodes,and the particles at these positions remain permanently at rest. Thus,the $Reason$ is also correct.However,the fact that some particles remain at rest (nodes) is a property of stationary waves,not the cause of why the medium must be bounded. Therefore,the $Reason$ is not the correct explanation of the $Assertion$.

$Assertion :$ For the formation of stationary waves,the medium must be bounded having definite boundaries.
$Reason :$ In the stationary wave,some particles of the medium remain permanently at rest.
