why sky is appearing blue?

Question

violet is the colour of less wavelength so it must scatter more than blue

Answer 1

It's due to a phenomenon called Rayleigh scattering. When light encounters particles much smaller than the wavelength of light, the light scatters. Atmospheric gas is an enormous resevoir of such particles. Short wavelengths scatter the most effectively, and blue has a short wavelength, so the blue light scatters and appears to fill the sky. Note that violet has a shorter wavelength than blue, but the human eye is not very good at seeing violet, so blue appears to dominate instead.

Answer 2

The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. Combined, these effects scatter (bend away in all directions) some short, blue light waves while allowing almost all longer, red light waves to pass straight through. When we look toward a part of the sky not near the sun, the blue color we see is blue light waves scattered down toward us from the white sunlight passing through the air overhead. Near sunrise and sunset, most of the light we see comes in nearly tangent to the Earth's surface, so that the light's path through the atmosphere is so long that much of the blue and even yellow light is scattered out, leaving the sun rays and the clouds it illuminates red.

Scattering and absorption are major causes of the attenuation of radiation by the atmosphere. Scattering varies as a function of the ratio of the particle diameter to the wavelength of the radiation. When this ratio is less than about one-tenth, Rayleigh scattering occurs in which the scattering coefficient varies inversely as the fourth power of the wavelength. At larger values of the ratio of particle diameter to wavelength, the scattering varies in a complex fashion described, for spherical particles, by the Mie theory; at a ratio of the order of 10, the laws of geometric optics begin to apply.

Answer 3

Simply speaking light from the sun looks white but it consists of 7 colours. Out of all the seven colour blue and violet colour have shorter wave length. When all the colours pass through atmosphere due to its longer wave length Blue and violet colours gets scattered all over the sky due to shorter wavelength, it is very difficult to see violet colour when it mixed with blue colour and hence the sky looks blue.

Answer 4

This is due the scattering of light by the atmosphere; The quantity of light scattered by the atmosphere is inversely proportional to the 4th power of the wavelength of the light; Violet and Indigo, though having very small wavelengths, are not fundamental colours; They are compound colours; So, they are not scattered; Next to Indigo is Blue, which is a fundamental colour; So, it is scattered profusely by the atmosphere; And, the Sky appears Blue;

Answer 5

sky is not exactly blue. it is infact dark in color when you see from the outer orbits of the sun. But it appears blue to our eyes on the earth due to light defraction

Answer 6

In atm. there are many suspended colloidal particles they have tendency of scattering of light, wave length of scattered light depend upon the size of particles.

Answer 7

The eye is not as sensitive to violet as it is to blue.

Answer 9

actually sky is not blue.
it is a reflector of the oceans.i.e., the color of ocean is reflecting in the sky clouds and it look like the sky is blue.

Answer 10

No you are wrong because sky color is not a blue, blue and blake
