Light waves are transverse waves. This means that the oscillations of the electric and magnetic fields, which make up the light wave, are perpendicular to the direction in which the wave is moving. In a transverse wave, the crests and troughs of the wave are also at right angles to the direction of travel. This is in contrast to longitudinal waves, where the oscillations occur in the same direction as the wave's travel, such as in the case of sound waves in air.

Transverse and longitudinal
waves.
Light and other types of electromagnetic radiation are
transverse waves. Water
waves and S
waves (a type of seismic
wave) are also
transverse waves. In
transverse waves, the vibrations are at right angles to the direction of travel.
