Sir,(adsbygoogle = window.adsbygoogle || []).push({});

Consider a progressive wave represented by the equation,

y = A[sin(wt – kx)]

If it is reflected from a wall, what will probably be the equation of the reflected wave?

I think it is y = A1[sin(wt + kx)]

Is it right? Should a negative sign be given to the expression? Will there be a phase change of pi assuming the wall to be rigid boundary?
