Robustness to scattering is a common requirement for communications and for imaging Why electrons can even be ejected from an They have produced light sources that for the first time emit high-intensity light in only one direction.
Yeah, you can forecast them to a certain degree. I guess it's a question of who cares—maybe filmmakers or photographers would find that information useful, but most people just want to know if it's going to rain or not. There's often a slanting band of clouds on the back side of the departing weather system, and that can act as a sort of projection screen for the low-sun colors, better than a horizontal band would.
The slant means it captures more of the orange and red light, and if the cloud is thin enough, it will reflect those colors down to you. Also, storms wash a lot of the big particles out of the air. Yes, true sunset occurs a minute or so before you see the sun disappear. What you see is a kind of mirage; the light is getting bent around the horizon by the effect of refraction. Our eyes are sensitive to a very tiny part of the spectrum of the sun's wavelengths, and that's responsible for the way we see our environment.
Other creatures seem able to see the ultraviolet area of the spectrum. We can only see a tiny part of what's going on. So a butterfly or a reindeer , which can perceive ultraviolet light, might be seeing a different, perhaps more colorful sunset than we do? The more you look at things, the more you realize how unique your own experience is as a human on this planet, at this particular place and time.
All rights reserved. In simple terms, what makes a good sunset happen? Do dust and air pollution make sunsets more dramatic? Do the seasons affect sunsets? So conversely, could local weather forecasters predict a pretty sunset? Why are sunsets sometimes more dramatic after a major storm? Is it true that by the time we see a sunset, the sun is actually already gone? Sounds like there's a lot of science to sunsets, but it's also a very subjective experience.

Why is the sky blue? Blue Sky Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules.
Contributors: Eileen Korenic and Joseph Shaw. For example, blue has a short wavelength, while red is created by longer wavelengths. At sunrise and sunset, the Sun is very low in the sky, which means that the sunlight we see has travelled through a much thicker amount of atmosphere.
Because blue light is scattered more strongly by the atmosphere, it tends to be scattered several times and deflected away in other directions before it gets to us. This means that there is relatively more yellow and red light left for us to see.
