Ultraviolet light is a part of the electromagnetic spectrum. Ultraviolet rays have frequencies greater than the frequency of visible light but lower than the frequency of X-rays. The wavelength of ultraviolet light is shorter than visible light and longer than that of X-rays. On interaction wit...
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 ...
Cataract surgery was revolutionised by the introduction of modern intraocular lenses in the late 1940's. By the late 1960's to 1970's evidence had emerged that short-wavelength light caused phototoxicity at the retina and retinal pigment epithelium. By the early 1980's ultraviolet filters had ...
What is the wavelength (in mm) of 5.3 million Hz ultrasound as it travels through human tissue? The wavelength, frequency, and speed of the sound wave: The wavelength of a wave is defined as the distance between two consecutive troughs or two consecutiv...
What is the frequency of a photon of ultraviolet radiation with a wavelength of 365nm?Ultraviolet Radiation:Ultraviolet radiation is one section of the electromagnetic spectrum. The range of wavelengths for ultraviolet radiation are between 400 nm - 10 nm. Ultraviolet radiation is divi...

For visible light, the wavelength is about 0.5 µm. But, even if the optical paths for each telescope are nominally identical, real-world effects of thermal expansion and vibration will produce time varying errors in the total path length that are far larger than the required value. To ...
A light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it in a process called electroluminescence. The wavelength of the light produced—and hence the color—depends on the type of semiconductors used. White light has been traditionally ...
Electromagnetic (EM) radiation possesses both the properties of a particle and a wave. As a wave it is a periodic oscillation, so it has a a certain wavelength, which is the distance over which the wave shape repeats. This wave shape repeats a certain number of times in one second, ...
Wavelength The distance between two successive points of a wave. The wavelength of red light is longer than that of blue light. 20 Frequency Regularity or repetitiveness of an event. The frequency of her visits has decreased over time. 5 Wavelength The distance between successive crests or troug...
