since the wavelength of the blue light passes through the particles with greater ease than the wavelengths of the other colors of light, the sky appear blue to the naked eye.这种现象说明了光线通过地球大气微粒时的物理散射方式。大气微粒的直径为有色光直径的十分之一。光谱是按波长由红...
It can measure long-wavelengths of light, such as those produced by traditional yellow-and-orange sodium-vapor street lamps. But VIIRS cannot see the short-wavelength blue light produced by white LEDs. This light has been shown to disrupt human sleep cycles and nocturnal animals' behavior....
根据第三段“ButVIIRS cannot see the short-wavelength blue light produced by whiteLEDs.”(但VIIRS无法看到白色led产生的短波蓝光。)及第四段“Theteam believes the ongoing switch to LEDs caused already brightcountries such as Italy, the Netherlands, Spain and the U. S. toregister as having stable...
Wavelength of Blue Light Visible light is a form of energy and part of the electromagnetic spectrum. Radio waves, microwaves, X-rays, and other kinds of light are also part of the electromagnetic spectrum, but visible light is the only part of it human eyes can see. ...
