Q. A stationary wave is represented by $y=A \sin (100 t) \cos (0.01 x )$, where $y$ and $A$ are in millimetres, $t$ is in seconds and $x$ is in metres. The velocity of the wave is

AIPMTAIPMT 1994Waves

Solution:

$\text { Velocity of wave } v =\text { coefficient of } t / \text { coefficient of } x =100 / .01=10^4 m / s$
