Electromagnetic waves are transverse waves. That means the electric and magnetic fields change (oscillate) in a plane that is perpendicular to the direction of propagation of the wave. Also note that electric and magnetic fields in an EM wave are also perpendicular to each other.

Do electromagnetic waves have longitudinal?

Although both wave types are sinusoidal, transverse waves oscillate perpendicular to the direction of propagation, while longitudinal waves oscillate parallel to the direction of propagation. ... All electromagnetic waves (light waves, microwaves, X-rays, radio waves) are transverse. All sound waves are longitudinal.

Why is electromagnetic waves transverse?

Electromagnetic waves are also transverse waves because the direction of particle displacement is also perpendicular to the direction of movement, producing the waveform of visible light, and other types of electromagnetic radiation.
