Which of the following is not a wave on the electromagnetic spectrum

A). Microwave

B). Visible Light Wave

C). Radio Wave

D). Surface Wave

D). Surface Wave

Explanation:

Surface waves are seismic waves and not an electromagnetic spectrum wave. These waves appear on the surface of a body of water and spread over the earth's surface. They have low frequency, long duration and are very destructive because of their great amplitude. Its spread on the surface arises from an earthquake. These waves can be Rayleigh waves or Love waves.

Microwave, visible light wave and radio wave are electromagnetic spectrum waves.

D is the answer to the question
