electromagnetic waves

Electromagnetic waves are waves that can travel through the vacuum of space and consist of oscillating electric and magnetic fields. They include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Gamma rays have the highest frequencies and the shortest wavelengths in the electromagnetic spectrum.

Ultraviolet light has a wavelength of approximately 10^-8 meters.

Radio waves have a wavelength of approximately 10^3 meters.

X-rays have frequencies higher than visible light.

The order is: Gamma rays, X-rays, Ultraviolet rays, Visible light, Infrared rays, Microwaves, Radio waves.

The speed of electromagnetic waves in a vacuum is approximately 299,792 kilometers per second (or about 300,000 km/s).

Frequency and wavelength are inversely related; as the frequency increases, the wavelength decreases, and vice versa.

Microwaves are used for cooking food, in communication technologies, and in radar.

Visible light is the portion of the electromagnetic spectrum that is visible to the human eye, with wavelengths ranging from approximately 400 to 700 nanometers.
