What type of wave is a microwave? a. heat b. longitudinal c. sound d. transverse

d. transverse

Explanation:

There are two kinds of wave: transverse and longitudinal. In a transverse waves, there is to ad for motion perpendicular to the motion of the wave. In longitudinal wave, there is to and fro motion of the medium particles in the direction of motion of the wave.

A microwave is an electromagnetic wave which is transverse in nature. The electric and magnetic field oscillate perpendicular to the motion of the wave.  It does not require medium to travel. It can move in vacuum as well with the speed of 3×10⁸ m/s. Thus, correct answer is microwave is a type of transverse wave.
