You have learnt that a travelling wave in one dimension is represented by a function y = f (x, t)where x and t must appear in the combination x – v t or x + v t, i.e. y = f (x ± v t). Is the converse true? Examine if the following functions for y can possibly represent a travelling wave:

(a) (x – vt)²

(b)

Q. Given below are some functions of x and t to represent the displacement (transverse or longitudinal ) of an elastic wave. State which of these represent (i) a travelling wave (ii) a stationary wave or (iii) none at all:
(a)

y = 2 c o s (3 x) sin (10 t)

y = 2 \sqrt{x - v t}

y = 3 sin (5 x - 0.5 t) + 4 cos (5 x - 0.5 t)

y = c o s x s i n t + c o s 2 x s i n 2 t
