What Are Standlng Waves?

1.	What Are Standlng Waves?
Answer» Two identical waves travelling towards each other INTERFERE in such a way as to produce one wave in which there are nodes that are fixed in position. This is called a STANDING wave. E.g. y(X, t) = cos(kx - wt) + cos(kx + wt) = 2 cos wt cos kx For all TIMES the function y(x, t) has nodes at kx = ODD multiples of Π/2. Two identical waves travelling towards each other interfere in such a way as to produce one wave in which there are nodes that are fixed in position. This is called a standing wave. E.g. y(x, t) = cos(kx - wt) + cos(kx + wt) = 2 cos wt cos kx For all times the function y(x, t) has nodes at kx = odd multiples of Π/2.
