Why Sky is Blue?

The sky appears blue to our eyes because blue light is scattered more easily than other colors of light. When sunlight reaches Earth's atmosphere, it is made up of a mixture of different colors, each with its own wavelength. Blue light has a shorter wavelength and is more easily scattered than other colors of light.

When sunlight hits the atmosphere, it is made up of a mixture of different colors, each with its own wavelength. Blue light has a shorter wavelength and is more easily scattered than other colors of light. This is why the sky appears blue during the day.

At night, the sky appears dark because there is no sunlight to scatter the light. However, when the sun is low on the horizon, such as at sunrise and sunset, the blue light is scattered even more, giving the sky a reddish or orange color.

The color of the sky can also be affected by other factors, such as dust and pollution in the atmosphere. These particles can scatter light in different ways, resulting in the sky appearing hazy or gray.

Overall, the blue color of the sky is a result of the scattering of light by the atmosphere. The shorter wavelengths of blue light are scattered more easily than other colors, giving the sky its characteristic blue hue.
