Sometimes the whole western sky seems to glow. The sky appears red because small particles of dust, pollution, or other aerosols also scatter blue light, leaving more purely red and yellow light to go through the atmosphere.

Why is the sky blue? A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
Why is the Sky Blue? On a clear sunny day, the sky above us is a brilliant blue. In the evening, the sunset puts on a beautiful show of reds, pinks and oranges. Why is the sky blue? What makes the sunset red? To answer these questions, we must learn about light, the Earth's atmosphere, and how these two things interact.
A colored piece of glass warms quickest because it absorbs more frequencies of light, thus converting the energy to temperature. ... Why does the sky normally appear blue? Air molecules have resonances in the ultraviolet, so they scatter blue light more than red light. ... Physics 1320 Exam 1. OTHER SETS BY THIS CREATOR. 90 terms. MC 3360 ...
Usually, the term sky is used informally as the point of view from the Earth's surface; however, the meaning and usage can vary. In some cases, such as in discussing the weather, the sky refers to only the lower, more dense portions of the atmosphere. During daylight, the sky appears to be blue because air scatters more blue sunlight than red.
The sky of Mars near the Sun appears blue, while the sky far away from the Sun appears red. The disk of the Sun appears mostly white, with a slight bluish tinge. ... which explains why distant ...
The answer taught in classrooms is: the sky is blue because blue is a short wavelength and air molecules scatter short wavelengths of light better than long wavelengths. Violet has a shorter wavelength than blue, but our eyes aren’t very sensitive to violet light. Blue light is less polarized than the other colors because it scatters more times and multiple scatterings destroy polarization.
The sky appears blue because . A) it is actually blue : B) the atmosphere scatters blue colours more than the others : C) all colours interfere to produce blue : D) in white light the blue component dominates: Correct Answer: B) the atmosphere scatters blue colours more than the others :
