In a transverse wave the distance between a crest and neighbouring trough at the same instant is 4.0cm and the distance between a crest and trough at the same place is 1.0cm. The next crest appears at the same place after a time interval of 0.4s. The maximum speed of the vibrating particles in the medium is :
Official answer
(2)
$\displaystyle \frac{5 \pi}{2} \mathrm{~cm} / \mathrm{s}$
