Electromagnetic Wave: Electromagnetic waves are a self-propagating transverse wave of oscillating electric and magnetic fields. The direction of the electric field is indicated in blue, the magnetic field in red, and the wave propagates in the positive x-direction. Notice that the electric and magnetic field waves are in phase.
Let's start with a picture of ocean waves; as seen from the side, they look like "sine" waves (just like BMS's red EM wave); as seen from the top, the crests and troughs make lines (not points). The same thing happens with the E and B waves (make lines), and since they are perpendicular to each other, they form a plane (two
Feb 16, 2023 · So, both EM waves and mechanical waves are determined by solving a wave equation. But EM waves must also satisfy the other parts of Maxwell's equations, namely Gauss's Law and $\nabla \cdot {\bf B} = 0$. These prohibit longitudinal oscillations of the the electric and magnetic fields.
Propagation of a transverse spherical wave in a 2d grid (empirical model) In physics, a transverse wave is a wave that oscillates perpendicularly to the direction of the wave's advance. In contrast, a longitudinal wave travels in the direction of its oscillations. All waves move energy from place to place without transporting the matter in the ...
transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves. A simple transverse wave can be represented by a sine or cosine curve, so ...

This nature of electromagnetic wave is known as Transverse nature. Maxwell proved that both the electric and magnetic fields are perpendicular to each other in the direction of wave propagation. He considered an electromagnetic wave propagating along the positive x-axis. When a rectangular parallelepiped was placed parallel to the three co ...
