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 traveling wave, (ii) a stationary wave or (iii) none at all:
`"y" = 2sqrt(x - "vt")`

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