Question

The waves in which the particles of the medium vibrate in a direction perpendicular to the direction of wave motion is known as
(a) Transverse waves
(b) Propagated waves
(c) Longitudinal waves
(d) Stationary waves

Answer 1

Waves can be categorized on the basis of direction of movement of the individual particles of the medium relative to the direction of the wave it travels. Now, on the same basis we will categorize longitudinal and transverse waves.

Complete step by step answer:
Now, in question we are asked that in which waves the particle of medium vibrate in the direction perpendicular to the direction of wave motion, first of all we will define all the waves,
Propagated waves are the main wave which is further categorized in longitudinal and transverse waves.
Stationary waves are the waves which remain stationary with respect to time or distance.
A wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves is called transverse waves. Transverse waves are as shown in the figure.

A wave in which particles of the medium move in a direction parallel to the direction that the wave moves is called longitudinal waves. Longitudinal waves are shown in the figure.

Thus, on considering the definitions and figures we can say that in transverse waves, the particles of the medium vibrate in a direction perpendicular to the direction of wave motion.

So, the correct answer is “Option A”.

Note: In transverse waves displacement of the medium is perpendicular to the direction of propagation of the wave. Examples of transverse waves are secondary waves of an earthquake, stadium or human wave electromagnetic waves and waves on a string.
