A wave characterized by oscillations perpendicular to the direction of wave travel is known as a transverse wave. In transverse waves, the particle motion occurs at right angles to the direction of wave propagation, as seen in waves on strings or electromagnetic waves, such as light. This contrasts with longitudinal waves, where particle motion is parallel to wave travel, as in sound waves. Understanding the characteristics of transverse waves is important in various fields, including physics, engineering, and telecommunications.
