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 ...

For thousands of years, humans were looking up at the star-studded night sky using just their eyes sensitive to the optical wavelength of the electromagnetic spectrum.The first telescopes ...

The electromagnetic spectrum is the range of all possible electromagnetic radiation. Above infrared in frequency comes visible light. This is the range in which the sun and stars similar to it ...

The new device, made by Liu Yang and colleagues from Zhejiang University in China, can for the first time, efficiently shield EMI in the X band (a frequency band in the microwave region) with an ...

The Sun appears here in ultraviolet light, which has a wavelength slightly shorter than that of visible light. Looking at the Sun in this portion of the electromagnetic spectrum highlights its ...

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 ...

By tuning the wavelengths of light coming out of the frequency comb, researchers can create a coherent spectral line that precisely corresponds to a particular quantum transition in an atom.

For future warfighters, researchers intend to push the outer limits, so to speak, of spectrum. “We’re going to really try to push the electromagnetic spectrum to its fullest extent,” Swindell says.
