  1. Discovered by Clerk Maxwell in 1864

Microwaves were first used for radar in WWII. (1939-1945) The development of microwaves is only one step of the gradual evolution of the concept and application of electromagnetic waves. Maxwell formulated a set of equations supporting all electromagnetic phenomena, which became known as Maxwell's equations. Hertz's experiment proved further generalizations and applications which led to the development of the microwave.

In some cases microwaves relieve symptoms better than drugs. The use of microwaves is safer than surgery. For example, the wave can heat enlarged prostates, therefore killing extra tissue.
