Question

The angle between particle velocity and wave velocity in a transverse wave is

• A. zero
• B. $ \pi /4 $
• C. $ \pi /2 $
• D. $ \pi $

Answer 1

The Correct Option is C

In a transverse wave the particles of the medium vibrate about their mean positions in a direction perpendicular to the direction of wave propagation.

Here, the particle velocity is given by $ \frac{dy}{dt}$ and
wave velocity is given by $ \frac{dx}{dt}$.
Hence, the angle between particle velocity and wave velocity ma transverse wave is $ \frac{\pi}{2}$
