Microwaves are the second lowest frequency and second longest wavelength electromagnetic waves.

Microwaves can cause alternating currents in metals.

Microwaves can travel through a vacuum as well as through gases in the Earth's atmosphere.

The speed of microwaves through a vacuum is 300,000,000m/s.

Transmitted - Microwaves can pass through a medium.
Absorbed - The energy transferred by microwaves can be taken in by certain materials, particularly metals.
Reflected - Microwaves can bounce off an interface between two media. This can be either Diffuse Reflection or Specular Reflection.
Refracted - Microwaves can change direction when they cross the interface between two media.

Microwaves can be used in communication because they can be created by alternating current and can cause an alternating current in metals.

Microwaves can be used for cooking because they cause water molecules and fat molecules to oscillate increasing the temperature of the food.

Microwaves can cause internal heating of living creatures because they are made of water which is heated by microwaves.
