Two waves, travelling along the same direction, are given by
y1 = a sin (w1t − k1x)
and y2 = a sin (w2t − k2x)
Suppose that w1 and k1 are respectively slightly greater than w2 and k2. (i) Derive an
expression for the resultant wave obtained by their superposition, and (ii) explain the
formation of wave packet.
