MCQ
A transverse wave is given by $y=A \sin 2 \pi\left(\frac{t}{T}-\frac{x}{\lambda}\right)$. The maximum particle velocity is equal to 4 times the wave velocity when
  • A
    $100 \mathrm{~m} / \mathrm{s}$
  • B
    $250 \mathrm{~m} / \mathrm{s}$
  • C
    $750 \mathrm{~m} / \mathrm{s}$
  • ✓
    $1000 \mathrm{~m} / \mathrm{s}$
✓

Answer

Correct option: D.
$1000 \mathrm{~m} / \mathrm{s}$
(d) $\quad v=\frac{\omega}{k}=\frac{100}{1 / 10}=1000 \mathrm{~m} / \mathrm{s}$
