y is the sky blue?

Question

how do we get the truem blue

whome invetin colours

Answer 1

The sky is blue because the water molecules in the air scatter that color more than the others.

...I have no idea what truem blue could be...

Unless you mean the True M, which is the University of Michigan, whose colors are Maize and Blue. How do you get UofM blue? Study!Study!Study!

Answer 2

The correct response is that light is scattered by air. All colors are scattered, but those with shorter wavelength are scattered more Violet is scattered even more, but the eye is less sensitive to that color (and it also averages with the green).

This has little to do with the presence of water, although water accentuates the phenomenon; you have the same recognizable blue in the dampness of Florida or in the dryest of the deserts. You don't get variation in sky color with changing humidity, as you'd expect if water was the decisive factor.

And it has nothing to do with the "prism effect" mentioned in the first answer; the explanation, even if it came from the science class, is totally wrong. If it was true, we'd see a ring of colours around the Sun, similar to the rainbow, A prism effect is actually seen at stars relatively close to the horizon, but the effect is so small that you need a telescope to se the colour decomposition.

Answer 3

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

Answer 4

The Light of the sun are in many different colors. Space acts as a prism and spreads the light and by chance over here by Earth we mostly get the blue color of the light.

Answer 5

It is due to the dispersion of light. The light from the sun undergoes refraction whn it passes through our atmosphere. whn it gets refracted the blue light is dispersed more than others by air molecules. Therefore the sky appears blue :)

Answer 6

It is the reflection of the ocean off of the atmosphere.
