Why does the sun appear reddish early in the morning

"All the burning and scathing has led to smoke particles being blown 2,000 kilometers away, piggybacking jet streams and crossing borders into the US. Apart from creating haze-like conditions over both countries, the smoke also filtered out sunlight in a very tricky way, making the Sun appear bloodshot," the outlet reported.

The same reason the sky is blue and the same reason sunset is sometimes green. Light is refracted through the atmosphere; different frequencies bend to a different angle. Because certain frequencies are associated with particular colours (the order of the rainbow represents an increase in frequency) and because the sun is at particular angles throughout the day, the frequencies that we see change as well. In the morning, it happens that the red end of the spectrum is the dominant part at that time The light from the Sun, when passing through the atmosphere, hits molecules of gases and the blue frequencies are spread in all directions (that is why the clear sky looks blue). What is not spread out are the yellow and red frequencies/energies, so the Sun appears redest when the light travels through the most atmosphere (sunrise and sunset)

However, light from the Sun overhead has to travel a lesser distance. At noon, the Sun appears whitish or yellowish as only little blue and violet light are scattered. However, near the horizon, most of the blue light and shorter wavelengths are scattered. Thus, the Sun appears reddish in colour during sunrise or sunset. Hope this helps!

Refraction makes celestial objects appear higher in the sky. Magic Atmosphere One of mother nature's favorite magic tricks, refraction is the bending of light as it moves from one substance to another. It is responsible for a variety of optical phenomena including The Mechanics of Refraction How much a light wave bends depends on its wavelength, the density of the substance it is moving into, and the angle at which it hits the edge of the substance. When light moves from a less dense to a more dense substance, like air to water or from a less dense layer of the atmosphere to a denser layer, it bends towards the normal—an imaginary line that is perpendicular to the surface of both media. The opposite occurs when light moves from a more dense to a less dense substance. The angle between the normal and the refracted light ray is known as the angle of refraction. If light enters a medium from another substance at a 90-degree angle, it does not refract and passes right through. Astronomical Refraction When the light of a celestial object, like the Sun, enters the Earth's atmosphere from space, the resulting refraction is known as astronomical refraction or atmospheric refraction. This is in contrast to terrestrial refraction that occurs when the source of light is from an object on Earth. The density of Earth's atmosphere is uneven—it decreases with increasing altitude. Light from celestial objects therefore refracts multiple times when it enters the atmosphere from space. Disp...

NCERT Solutions for Class 10 Science Chapter 11 - Do you know that the human eye has a lens in its structure? What is the function of this lens? Such interesting questions are answered with examples in NCERT Class 10 Science solutions chapter 11. Human eye is the most valuable and sensitive sense organ. Some of the topics which are covered in Human Eye and Colourful World Class 10 chapter are the human eye, defects of vision and their correction, refraction of light through a prism. NCERT Solutions for Class 10 Science Chapter 11 - Topic 11.2 Defects of vision and their correction: Q.1. What is meant by power of accommodation of the eye? Answer: The power of accommodation is the ability of an eye to focus near and far objects clearly and making image on the retina by adjusting its focal length. However, the focal length of the eye lens cannot be decreased below a certain minimum limit. Q.4. Answer: Since the student has difficulty reading the blackboard while sitting in the last row, he is most likely to suffer from the disease of myopia (short-sightedness) i.e., he can see the closer objects clearly but unable to see the far objects properly. Hence it can be corrected by placing the spectacles with concave lenses of appropriate power. The Human Eye and The Colorful World Exercise Solutions: Q.1. The human eye can focus on objects at different distances by adjusting the focal length of the eye lens. This is due to (a) presbyopia. (b) accommodation. (c) near-sightedness. (d...

Blue light scatters easily in the atmosphere so the daytime sky appears blue. When the Sun is low in the sky, sunlight has to travel farther through the atmosphere, the blue light is scattered away, and the sky and Sun appear red. ©timeanddate.com Made of Different Colors The sunlight that we see is a type of electromagnetic radiation that is emitted by the Sun. Known as the visible light, it looks white but is composed of colors of different wavelengths, with violet having the shortest wavelength and red having the longest. You can see the different colors when you look through a prism or when a Earth’s Atmosphere The Earth’s atmosphere is primarily made up of gas molecules, with oxygen comprising about 21% and nitrogen about 78%. In addition, water molecules in the form of droplets, ice crystals, and vapor, and particles such as dust, pollutants, and ash can be found in the atmosphere, which is denser closer to the Earth and thins out as the altitude increases. The Sun's rays have to travel a shorter path through Earth's atmosphere in the day. This is why the sky looks blue during the day. ©iStockphoto.com/bluejayphoto Blue Skies And Yellow Sun When sunlight strikes gas molecules, such as nitrogen and oxygen, light of longer wavelengths, like red, yellow, and orange, easily passes through, while light of shorter wavelengths, such as blue and violet, is absorbed and then scattered in all directions by the gas molecules. When you look up at the sky during the day, this sca...
