Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
A standing wave pattern is a vibrational pattern created within a medium when the vibrational frequency of the source causes reflected waves from one end of the medium to interfere with incident waves from the source. This interference occurs in such a manner that specific points along the medium appear to be standing still. Because the observed wave pattern is characterized by points that appear to be standing still, the pattern is often called a standing wave pattern. Since the vibrations of all points are still in their position, there is no transfer of energy.Hence correct answer is option A.
