Final answer:
Electromagnetic waves that travel through a vacuum are transverse waves, not longitudinal waves. They have oscillations perpendicular to the direction of travel, which allows them to propagate through a vacuum without a medium.
Electromagnetic waves that travel through a vacuum are:
Transverse waves
Step-by-step explanation:
Electromagnetic waves that travel through a vacuum are not longitudinal waves. They are actually transverse waves. Unlike longitudinal waves, which have oscillations parallel to the direction of travel, electromagnetic waves have oscillations perpendicular to the direction of travel.
This perpendicular oscillation allows electromagnetic waves to propagate through a vacuum without the need for a medium.
Electromagnetic waves that travel through a vacuum are:
Transverse waves
Electromagnetic waves, such as light and radio waves, are transverse in nature, meaning that the electric and magnetic fields oscillate perpendicular to the direction of wave propagation.
Electromagnetic waves that travel through a vacuum are transverse waves, not longitudinal waves. They have oscillations perpendicular to the direction of travel, which allows them to propagate through a vacuum without a medium.
