This discovery meant that light was no more than an electromagnetic wave, part of the electromagnetic spectrum. Like all waves, light’s nature is defined by its wavelength – the distance ...

The electromagnetic spectrum is a rainbow of light waves that surround us — but we only see a small part of it. From radio waves to gamma rays, each type of light has its own properties and uses. By ...

Electromagnetic Spectrum Tour. By Rick Groleau; Posted 01.08.02; NOVA; Light, heat, radio signals, and medical X-rays are all forms of electromagnetic radiation—waves moving through space that ...

There's lots to discover in the electromagnetic spectrum. Here's a tour that begins with radio waves and takes you through microwaves, infrared radiation, light, ultraviolet radiation, and X-rays.

Each type of wave in the electromagnetic spectrum has a different: wavelength. frequency close frequency The number of waves produced each second. The unit of frequency is hertz (Hz).

Unlike submillimeter waves, infrared light spans a vast range of the electromagnetic spectrum from 0.04 inches (just below 1 millimeter) on the side bordering with microwaves to 0.75 micrometers ...

The electromagnetic spectrum, from highest to lowest frequency waves. The electromagnetic spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy ...
