Inwirelesssystems, wavelength is usually specified in meters (m), centimeters (cm) or millimeters (mm). In the case of infrared (IR), visible light, ultraviolet (UV) and gamma radiation (γ), the wavelength is more often specified in nanometers (nm) or angstroms (Å). Nanometers are ...
Strong terahertz (THz) electric and magnetic transients open up new horizons in science and applications. We review the most promising way of achieving sub-cycle THz pulses with extreme field strengths. During the nonlinear propagation of two-color mid-i

Imaging evanescent waves is of crucial importance for sub-wavelength-scale investigation of various phenomena. However, frequently used techniques for near-field imaging require either a strong perturbation of the field, long acquisition times or complex electron-based tools. Here, we introduce nonlinear...

Wavelengths of Light and ColorsVisible light has wavelengths between roughly 400 nm and 750 nm; there is also infrared light with longer wavelengths and ultraviolet light with shorter wavelengths. As such wavelengths are rather small, light exhibits much weaker diffraction effects than sound waves, ...
infrared waves D. ultraviolet waves Light, x-rays, microwaves, and radio waves are examples of which type of energy? What type of electromagnetic radiation has the highest energy? What is the relationship among frequency, wavelength, and wave speed? A. What is the wavelength (in nan...
visible spectrum- the distribution of colors produced when light is dispersed by a prism color spectrum spectrum- an ordered array of the components of an emission or wave electromagnetic spectrum- the entire frequency range of electromagnetic waves ...
(Science: radiobiology) The length of a single cycle of a wave, usually measured from crest-to-crest. For electromagnetic waves, the wavelength determines the type (radio, infrared, visible, ultraviolet,x-Ray, gamma-ray) ofradiation, in the case ofvisible light, wavelength determines the colour...
