A lower frequency indicates a longer wavelength, stronger diffraction capability, poorer penetration capability, smaller signal loss attenuation, and longer transmission distance. Although the 5 GHz frequency band can bring a higher transmission speed, the signal attenuation is larger. Therefore, the ...
Yellow has a shorter wavelength than red but a longer wavelength than green. This means that red is visible the furthest away, yellow in the middle and green the least distance away—a helpful advanced warning for needing to slow or stop. But this could be a coincidence. Red meaning stop ...
One of the ways that the social media phenomenon has changed conversation for the worse is that it has taken us back to a kind of adult playground – one in which ‘virtual’ bullies crowd around you and jeer, in which you feel alone and friendless, in which you have no way of seeing...
shorter wavelength. People with protanomaly have a hard time seeing reds and discriminating colors across the entire normal visual spectrum. Finally, tritanomaly is an extremely rare (0.01% male and female) form of color
A better option, in my opinion, is to use amber-lensed goggles once the sun has gone down. These blue-blocking lenses are highly effective in reducing the effects of blue light exposure, and in most cases completely eliminate the short-wavelength radiation necessary for nocturnal melatonin suppre...
Gamma rays can have a wavelength of 10^-20 of a metre but radio waves at the other end of the spectrum can have wavelengths of kilometres. The balancing factor here is frequency where small wavelengths have very high frequency and very long wavelengths have low frequency. So how does ...
Momentum is used to find wavelength per deBroglie. That is a significance of momentum which could be important regardless of conservation. Yes, that would be a counter-example, unless the derivation of the deBroglie equations depends on momentun conservation itself. I wasn't thinking about ...

However the response is not to a precise wavelength, just are most sensitive to wavelengths in a general range. That gives six possible combinations that our visual cortex can process, rg, rb, gr, gb, bg, br, to associate a colour to an object. We also have sensors which don'...
