Why sky look blue

The sky is actually our atmosphere. It is made up of different types of gas water vapor. Due to the gravitational force of the earth, it surrounds the earth from all around. The higher you leave the earth, the lighter the atmosphere will be. And gradually it will no longer exist. That is why there is no atmosphere in space.

Why sky is blue?

There are tiny dust particles floating in the atmosphere around the earth. When light from the sun reaches the earth, it is scattered by those particles. And because blue light has a shorter wavelength, it is the most scattered, according to Rayleigh’s scattering formula. Due to which the sky looks blue in daylight. And at night there is no scattering due to the absence of sunlight and the sky looks black.

Then we need to know about sunlight. We see gold in sunlight but it is actually a mixture of the seven colors of the rainbow. There are seven colors of rainbow in sunlight. There is a specially shaped crystal called a prism in sunlight if ever needed. Then you will see that the light will be divided into seven colors.

Previously it was thought that vapor and dust were all responsible for the blue color of the sky. But later scientists studied and found that if vapor was also the cause of the scattering, then the color of the sky would look different in one place due to the difference in humidity, fog, etc. in different places! So they decided that the oxygen and nitrogen molecules in the various layers of the sky were enough to cause the sky to turn blue.

However, a question may arise, if the wavelength of purple light is less than that of blue light, then why does the sky not look purple?

First, the scattering of light rays in the atmosphere is not the same for all wavelengths. At the same time the atmosphere is so high above the earth’s surface that much of that purple light is absorbed into the atmosphere as the scattered light reaches it.

Second, the human retina contains three types of cone cells. They are most sensitive to red, blue and green light than other colors. We see different colors due to the combination of sensitivity of different proportions of these angles. Our eye cells are not ‘ultraviolet’ light-sensitive. For this reason, the sky does not seem dark purple to people.

It is pertinent to note that as the blue light continues to scatter more towards the bottom of the earth’s surface, the color of the sky near the horizon gradually becomes paler.
