Why is the sky blue

As white light passes through our atmosphere, tiny air molecules cause it to 'scatter'. The scattering caused by these tiny air molecules (known as Rayleigh scattering) increases as the wavelength of light decreases. ... Therefore, blue light is scattered more than red light and the sky appears blue during the day.

What causes the blue color of the sky?

The sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength. ... These shorter wavelengths correspond to blue hues, hence why when we look at the sky, we see it as blue.

Is it true that the sky is blue because of the ocean?

You asked about the sky. We know the sky is blue and the sea does reflect some of this light. So, yes, it does play a role. To sum it all up: the sea is blue because of the way water absorbs light, the way particles in the water scatter light, and also because some of the blue light from the sky is reflected.

What color is the sky really?

As far as wavelengths go, Earth's sky really is a bluish violet. But because of our eyes we see it as pale blue.
