Question

what type of wave is an electromagnetic wave? *
a. longitudinal
b. transverse
c. mechanical

Explanation:

Electromagnetic waves have electric and magnetic fields that oscillate perpendicular to the direction of wave - propagation, which is the characteristic of transverse waves. Longitudinal waves have particle motion parallel to wave - propagation. Mechanical waves require a medium to travel, while electromagnetic waves can travel in a vacuum.

Answer:

B. transverse
