what type of wave are electromagnetic waves, such as radio waves, microwaves, and infra - red waves…

Brief Explanations:

Electromagnetic waves, including radio waves, microwaves, and infra - red waves, are transverse waves. Transverse waves have oscillations perpendicular to the direction of wave propagation. In electromagnetic waves, the electric field ((\vec{E})) and magnetic field ((\vec{B})) oscillations are perpendicular to each other and also perpendicular to the direction of wave travel (denoted by (c) in the diagram). Compression waves (longitudinal waves) have oscillations parallel to the direction of propagation, which is not the case for electromagnetic waves.

Answer:

transverse
