Sky appears blue because air molecules scatter light with shorter wavelengths more effectively than longer ones, giving an impression of a bluer sky than would exist without atmosphere. Without it, however, skies would appear black.
Telugu, part of the Dravidian language family, is spoken in southeastern India. Alongside Tamil and Kannada it forms part of India’s wide variety of spoken languages that also includes Malayalam.
Blue Light
The sky appears blue due to how sunlight interacts with Earth’s atmosphere. Sunlight comes in various colors, but our eyes are most sensitive to blue and violet wavelengths. When sunlight enters our atmosphere, it hits molecules of nitrogen and oxygen in our air that are most active at those frequencies, scattering wavelengths into patterns which give rise to Rayleigh scattering (which gives the blue hue). Other wavelengths containing red or green components are either absorbed by air molecules or reflect off them back out again creating white skies instead.
The ocean appears blue because its color reflects that of the sky; however, that isn’t actually why our seas and oceans appear that way; they actually reflect their chemical makeup; specifically salts and other minerals found within its waters have properties which absorb light at specific wavelengths, thus dissipating waves reaching our eyes that otherwise would have been more intense.
As long as we’re discussing sky color, it is worth remembering that not all planets share our blue hue. This is due to the fact that not all have an atmosphere and without one sunlight would pass straight through its surface into space and cause the planet to appear dark. Our own planet does have an atmosphere, however, and particles found within its layers excel at scattering short wavelengths of light (blue) more efficiently than they can red wavelengths (which would produce dark skies).
At last, it is essential to remember that the shade of sky-blue can change depending on the time of day. At sunrise and sunset, sunlight travels further through the atmosphere and causes more blue wavelengths to scatter more than at other times of the day, creating different hues such as red, orange and pink – even red!
Indi-Aryan languages usually differentiate blue from green by adding prefixes or suffixes to words related to color; for example in Telugu the term for blue is nyl nila while Bengali uses the phrase fyrwzy ferozi. Other languages use one term that encompasses both hues simultaneously such as Hindi’s nil nila or Marathi’s hirvaa hirava for this color category.
Atmosphere
The sky is an ever-evolving natural phenomenon of varied color and depth, filled with clouds, sunbeams and the occasional rainbow. It serves as home for animals, birds and other living things as well as aircraft, kites and other human inventions; its color comes from air molecules scattering light molecules that give it its distinctive blue hue.
As sunlight enters our atmosphere, air molecules scatter it into different directions – with blue wavelengths getting dispersed more than any other color due to being shorter wavelengths and getting dispersed more by air molecules than others. Furthermore, human eyes are particularly sensitive to blue light so our perception of sky as blue becomes stronger than any other hues.
Even though the atmosphere is the primary influence on sky color, its hue can also be changed by other factors. If there is too much pollution in the atmosphere, for instance, its hue may change to gray or white; dust and aerosols in the atmosphere can alter its hue by desaturating it.
While this rule generally holds, there can be exceptions. When there is too much smoke in the air, it can make the sky appear yellow or orange and distort its colors; additionally, smoke may alter its colors so much as to cause it to seem smaller or larger than usual.
Near the horizon, the sky appears lighter because sunlight must travel farther through the atmosphere before becoming scattered more times, leading to its blue color becoming gradually less vivid until eventually it fades and turns a paler shade of white.
On other planets, skies appear blue due to thin atmospheres; however, their color may differ depending on their conditions and individual planet. Mars has an atmosphere thinner than that found here on Earth but is still blue for similar reasons; other atmospheres consist of different gases and particles which affect how their color changes over time; some planets like Venus and Mercury have thicker atmospheres which makes them harder to view due to opaqueness.

Meteorologists attribute the vibrant blue skies across India to an incredible natural phenomenon, caused by low cloud cover, sunshine and rain-washed clean atmosphere – without cloud cover, sunshine or rain-washed clean atmosphere; meteorologists said. Although only seen temporarily and enjoyed by everyone present. According to meteorologists, sunlight absorbing atmospheric gases causes light from shorter wavelengths (reddish light) to get scattered less, which makes the sky appear bluer than usual.
Sunlight contains all the colors of the rainbow, yet when it reaches Earth’s atmosphere it appears blue due to air molecules scattering it more than reddish wavelengths (longer wavelengths). This process, known as Rayleigh scattering, is due to physical properties found within air and gases.
White light travels through the atmosphere and is scattered by reflection off particles of dust, droplets of water and other substances found in the air, reflecting back into all directions; our eyes are most sensitive to shorter blue wavelengths which cause our vision to concentrate on these colors; when conditions allow we can observe both Sun, Moon and stars at once!
But what happens when it’s cloudy? We only see the bottoms of the clouds; as for why their tops appear blue – that is because the air between them has turned it so.
Answering this question involves studying our atmosphere’s composition for centuries. Tyndall and Rayleigh believed that blue skies could be caused by small particles or droplets of water in the atmosphere causing the color change; this however turned out to be incorrect.
Atmospheric nitrogen and oxygen combine to give our atmosphere its blue hue, scattering blue-violet light more readily than red or orange light waves due to shorter wavelengths being readily absorbed by gas molecules than longer red-orange wavelengths.
Sun
The blue sky has long fascinated people. Its composition, physical properties and behavior of light combine to produce this natural marvel that continues to mesmerize humans today. The colour blue is caused by scattering of sunlight by air molecules; red, violet and green wavelengths scatter less strongly, leading to its strong reflection back onto surfaces such as grass. Therefore, during daylight hours it appears blue whereas it remains so at night except when partially obscured by clouds.
When the Sun is high in the sky, its light travels through more atmosphere before reaching our eyes – this means more blue and violet wavelengths are dispersed by this process and less reach your vision; hence why skies nearer the horizon appear paler than those directly overhead.
As the Sun lowers in the sky, its light must travel through even more of the atmosphere before reaching you, which means more blue and violet wavelengths are diverted away from reaching our eyes, creating dark blue or bluish-violet skies directly overhead.
One reason the sky appears bluer may be our eyes’ greater sensitivity to shorter wavelengths such as blue and violet light; we’re less affected by longer wavelengths like green and red that may be scattered by air molecules; they don’t affect us nearly as strongly.
White light is actually composed of multiple hues, but when exposed to water droplets or particles in the atmosphere, its constituent parts become distinguishable and separated out into individual wavelengths – most prominent among which is blue light which scatters more readily than its fellow colors and appears more prominently than them all.
Polarized light from the Sun aligns its electric fields with those found in Earth’s atmosphere, giving an impression that it moves across the sky during the daytime hours. When this polarization is destroyed through multiple scattering, its appearance changes, making the Sun appear slower; similarly, Moon and planets appear slower than stars due to this same effect.
