sky:mvxki0-luo4= blue: Why is the Sky Blue?

In physics, whether remember or not, we were taught about the phenomenon “Rayleigh Scattering”. The sunlight is made up of a spectrum of colours. Each colour has its wavelength. We know that our atmosphere is filled with gases like nitrogen and oxygen. When sunlight enters our atmosphere it collides with the atmospheric gasses.

The light rays having shorter wavelengths like blue and violet, scatter in all directions. Although violet light is scattered even more than blue light, our eyes are more sensitive to blue wavelengths, which is why we see the sky as blue during the day.

The sky does not always appear blue. It changes colours throughout the day. The colour of the sky mainly depends on the position of the sun and atmospheric conditions on that particular day. For example, during sunrise and sunset, the sun is lower and sunlight has to pass through a greater thickness of the earth’s atmosphere. Resultantly, much of the light is scattered out and we see only longer wavelength lights like red, orange and pink.

On cloudy days, the water droplets scatter all wavelengths of light equally. That is why during forecast conditions, the sky appears gray or white. As the sun sets, the earth rotates away from sunlight. So the sky changes its colour from orange or red during sunset & sunrise, blue in daylight and dark or black in night time.

When sunlight strikes with pollutant particles it reflects the same wavelength light turning our sky from blue to foggy or gray color.
