When the direction of vibration of the particles of a medium is perpendicular to the direction of propagation of a wave, the wave is said to be——–
The correct answer is: B
Explanation
In physics, a transverse wave is a wave whose oscillations are perpendicular to the direction of the wave's advance.
This is in contrast to a longitudinal wave which travels in the direction of its oscillations. Water waves are an example of transverse wave.
