A transverse wave is a moving wave consisting of an oscillation that occurs perpendicularly (right elbow) to the energy transfer (or wave propagation).
If the transverse wave moves in the positive x direction, the oscillation is up and down located in the y-z field.
Light is an example of transverse waves, while sound is a longitudinal wave. The ripples in the pond and the waves on the rope are easily visualized as transverse waves.

Description
Transverse waves are waves that oscillate perpendicularly (at right angles) in the direction of propagation. If you are anchoring one end of a ribbon or a string and holding the other end in your hand, you can make transverse waves by moving your hands up and down. Pay attention though, you can also launch a wave by moving your hand sideways. This is an important point. There are two independent directions where wave motion can occur. In this case, this movement is Y and X the direction mentioned above, while the wave propagates away in the direction of z . Another type of wave is a longitudinal wave, which oscillates in the direction of its propagation.
"Polarized" Waves
Continuing with a string example, if you move your hand in a circle clockwise, you will launch a wave in the form of a left-handed helix as they spread. Similarly, if you move your hand in a circle counterclockwise, a right-handed helix will form. This simultaneous motion phenomenon is in two directions beyond the wave type we observe on the surface of the water - in that the waves on the string can be two dimensions .
The two-dimensional transverse wave shows a phenomenon called polarization. The waves generated by moving your hand in a straight line, up and down for example, are linearly polarized waves, a special case. The waves generated by moving your hand in a circle or ellipse are circularly polarized or elliptical waves, two other special cases.
Electromagnetic waves
Electromagnetic waves behave in the same way. Electromagnetic waves are also two-dimensional transverse waves. Transverse waves are waves that travel perpendicular to the direction of vibration. Ray's theory does not describe phenomena such as interference and diffraction, which require wave theory (involving wave phases). You can think of light rays, in optics, as the ideal electromagnetic radiation beam. The rays are used to model the propagation of light through an optical system, by dividing the real field of light into a discrete ray that can be reproduced computationally through a system with ray-tracking techniques. Light rays are lines or curves perpendicular to the face of light waves (and therefore are cholinear with wave vectors). Light rays bend at the interface between two different media and can be curved in the medium where the refractive index changes. Geometric optics explains how rays propagate through an optical system.
This two-dimensional nature should not be equated with the two components of electromagnetic waves, electrical and magnetic field components, as indicated in the light-wave diagram here. Each of these fields, electricity and magnetism, shows the behavior of two-dimensional transverse waves, like waves on a string.
