Infrared

Electromagnetic waves with frequencies lower than visible light, used in communication and heating by radiation.

Microwaves

Electromagnetic waves used in communication and heating, with frequencies higher than infrared.

Radio waves

Electromagnetic waves produced by oscillation, used in communication.

Ultraviolet

Electromagnetic waves with frequencies higher than visible light, used to disinfect water and can damage DNA and cells.

X-ray

Electromagnetic waves used in medicine to take images of the inside of the body, can cause mutations to DNA.
