Far-infrared, from 300 GHz to 30 THz (1 mm – 10 μm). The lower part of this range may also be called microwaves or terahertz waves. · Mid-infrared, from 30 THz ... History and discovery · Regions · Types of radiation |
Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. |
Electromagnetic radiation can be expressed in terms of energy, wavelength, or frequency. Frequency is measured in cycles per second, or Hertz. Wavelength is ... |
Beyond the red end of the visible spectrum is infrared radiation. This ranges from 700nm down to 0.1cm. We feel such radiation from a heat lamp but we cannot ... |
From long to short wavelength, the EM spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays. |
5 нояб. 2020 г. · X-rays are electromagnetic waves with wavelengths in the range of 0.01 to 10 nanometers and energies in the range of 100 eV to 100 keV. |
