Question

electromagnetic waves are a special type of
transverse wave
longitudinal wave
ocean wave
mechanical wave

Explanation:

Electromagnetic waves are transverse waves. Transverse waves are waves in which the oscillations are perpendicular to the direction of wave propagation. In electromagnetic waves, the electric and magnetic fields oscillate perpendicular to each other and also perpendicular to the direction of wave travel. Longitudinal waves have oscillations parallel to the direction of wave propagation (e.g., sound waves). Ocean waves are a type of mechanical wave (which require a medium), but electromagnetic waves do not need a medium (they can travel in vacuum).

Answer:

Transverse wave
