Choose the correct option for the following Assertion (A) and Reason (R).
Assertion
A transverse displacement wave reflected from a perfectly free end does not undergo a phase reversal.
Reason
At a perfectly free end the transverse force must vanish, which imposes the boundary condition ∂y/∂x = 0 at the end.
