Question

what type of wave is a microwave?
heat
longitudinal
sound
transverse

Explanation:

Microwaves are electromagnetic waves. Electromagnetic waves are transverse waves. Transverse waves have oscillations perpendicular to the direction of wave propagation. Heat is not a wave type classification here. Longitudinal waves (like sound) have oscillations parallel to wave direction. Sound is a mechanical longitudinal wave. So microwaves are transverse.

Answer:

D. transverse
