Types of Light Waves

Gamma Rays: Nuclear Energy
Gamma Rays: Nuclear Energy

Gamma-rays can be used to treat cancer, and gamma-ray bursts are studied by astronomers. Electromagnetic (EM) radiation is transmitted in waves or particles at different wavelengths and frequencies. This broad range of wavelengths is known as the electromagnetic spectrum.

Infrared Waves: Invisible Heat
Infrared Waves: Invisible Heat

Infrared radiation is a type of electromagnetic radiation, as are radio waves, ultraviolet radiation, X-rays and microwaves. Infrared (IR) light is the part of the EM spectrum that people encounter most in everyday life, although much of it goes unnoticed. It is invisible to human eyes, but people can feel it as heat.

Microwaves: Data and Heat
Microwaves: Data and Heat

Microwaves fall in the range of the EM spectrum between radio and infrared light. Microwaves have frequencies ranging from about 1 billion cycles per second, or 1 gigahertz (GHz), up to about 300 gigahertz and wavelengths of about 30 centimeters (12 inches) to 1 millimeter (0.04 inches), according to the Encyclopedia Britannica.

Radio Waves

Light vs Radio Waves Energy is one of the primary constituents of the universe. It is conserved throughout the physical universe, never created or never destroyed but transforming from one form to another.

Ultraviolet Waves: Energetic Light
Ultraviolet Waves: Energetic Light

The spectrum is generally divided into seven regions in order of decreasing wavelength and increasing energy and frequency. The common designations are radio waves,microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma-rays. Ultraviolet (UV) light falls in the range of the EM spectrum between visible light and X-rays.

Visible Light Rays
Visible Light Rays

Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Generally, visible light is defined as the wavelengths that are visible to most human eyes.

X-Rays: Penetrating Radiation
X-Rays: Penetrating Radiation

X-rays are a form of electromagnetic radiation, as are radio waves, infrared radiation, visible light, ultraviolet radiation and microwaves. One of the most common and beneficial uses of X-rays is for medical imaging. X-rays are also used in treating cancer and in exploring the cosmos.
