Question

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:
$\text{y}=2\sqrt{\text{x}-\text{vt}}$

✓

Answer

The given equation does not contain any harmonic term. Therefore, it does not represent either a travelling wave or a stationary wave.
