因为可见光的波长比构成玻璃的原子的直径长几百倍，所以原子的具体详情对描述原子与光线之间的相互作用并不重要。(最快回答好像是用软件翻译的)
How does the behavior of the light beam differ from the behavior of a bullet fired in the same direction from the top of the freight car? What is the difference between an open and a globular star cluster? Why would a laser dot sight become bigger the farther away its pointed?
radiation. At one end of the spectrum are gamma rays, which have the shortest wavelengths and high frequencies. At the other end are radio waves, which have the longest wavelengths and low frequencies. Visible light, with intermediate wavelengths and frequencies, is near the center of the ...
Light was an electromagnetic wave of the human eye can see, also known as the visible spectrum. In the definition of science, just means all of the electromagnetic spectrum. Light photons is composed of elementary particles, a particle nature and volatility, called wave-particle duality. Light ...
Light sources and illuminants are often confused. A light source can be turned on and off and be used to view an object. An illuminant is a mathematical description of a light source. Illuminants may describe light sources that do not actually exist in the laboratory. The current ‘D’ se...
In live cell fluorescence microscopy, for example, cells are exposed to excitation light of a certain wavelength. In optogenetic approaches, light of a certain wavelength is used as an optical actuator to switch on or off specific activities in the genetically modified cells, thereby modulating ...
Kiki… 有许多事学会… 她在哪里将有时间?[translate] aLong-wave radiation energy is a form of heat while short wave radiation energy is visible light from the sun 当短波辐射能量是可见光从太阳时,长挥动辐射能量是热的形式[translate]
Today we recognize that light possesses both a wave and particle nature. It is also clear that the limits of visibility really extend from about 310 nm in the ultraviolet (in youth) to about 1100 nm in the near-infrared, but depend very much on the radiance, that is, 'brightness' of ...
What kind of wave is light? What is the approximate range of wavelengths of electromagnetic waves? What is an example of visible laser radiation? What wavelengths can humans see? What is apparent visual magnitude? What is an instrument that separates light into various wavelengths? What is a co...
The related knowledge of Optics and terminology of visible light The related knowledge of Optics and terminology of visible light The following light and electromagnetic waves: Light is an electromagnetic wave, the speed: 30 x 10000 km/s wavelength was 780 ~ 380nm (nm), 1 nm =10-9 meters ...
