MCQ
A transverse wave propagating along $X-$axis is represented by
$\text{y (x, t)}=8.0\sin(0.5\pi\text{x}-4\pi\text{t}-\frac{\pi}{4})$
where $x$ is in metre and $t$ is in seconds. The speed of the wave is:
  • A
    $8\ \text{m/s}$
  • B
    $4\pi\ \text{m/s}$
  • C
    $0.5\pi\ \text{m/s}$
  • $\frac{\pi}{4}\ \text{m/s}$

Answer

Correct option: D.
$\frac{\pi}{4}\ \text{m/s}$
