The suspended particles should change the colour of the light in the bottle or glass to a bluish[带蓝色的] tinge[淡色], with the light on the paper having a reddish tinge. The blue part of the light (shorter wavelength) from the torch should be reflected and scattered by the particles ...

being received through our eyes. Therefore, the importance of thoughtful lighting design should not be underestimated, as it can attract potential customers and enhance their shopping experience. Neglecting to strategically utilize lighting can result in missed opportun...
Natural red fluorescence is particularly conspicuous in the eyes of some small, benthic, predatory fishes. Fluorescence also increases in relative efficiency with increasing depth, which has generated speculation about its possible function as a “light organ” to detect cryptic organisms under bluish li...
By contrast, molecules of low temperature reflect bluish or purple light because the tendency of heat is to move toward them. There are other reasons, aside from heat, that some objects tend to be red and others blue—or another color. Chemical factors may be involved: atoms of neon, for...
Peter Cooper Hewitt created the first commercial mercury-vapor lamp operating at a lower voltage. This is considered as the foundation for the development of modern fluorescent lamps. His lamp emitted a bluish-green color, which was unpleasant and nonsuitable for practical applications despite its su...
emit a distinctly bluish glow. “If you’re trying to illuminate a red object with a white LED that only has blue and yellow in the spectrum, you’re not going to get a very nice-looking red,” warns Kathryn Conway of the Lighting Research Center at Rensselaer Polytechnic Institute. That...
Some consumers began to rebel with such blue-rich lamps and demanded less 'harsh,' less 'cold-bluish' light sources. You will now find some LEDs and CFLs with greatly reduced blue emission. Nevertheless, in the past 60 years there has been an ever-increasing color temperature of artificial ...
Generally speaking, incandescents sit at the bottom of the scale with their yellow light, while CFLs and LEDs have long been thought to tend toward the high, bluish end of the spectrum. This has been a steady complaint about new lighting alternatives, as many people prefer the warm, familiar...
Some people also prefer the look of incandescent light, feeling they're warmer than the yellowish-looking CFL bulbs and the bluish brightness of LEDs. The difference in lighting types can take some adjustment, but LEDs are also available in a variety of hues. LEDs are dimmable (unlike CFLs)...
