why is the sky blue?

Answer 1

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.The white light from the sun is a mixture of all colours of the rainbow. This was demonstrated by Isaac Newton, who used a prism to separate the different colours and so form a spectrum. The colours of light are distinguished by their different wavelengths. The visible part of the spectrum ranges from red light with a wavelength of about 720 nm, to violet with a wavelength of about 380 nm, with orange, yellow, green, blue and indigo between. The three different types of colour receptors in the retina of the human eye respond most strongly to red, green and blue wavelengths, giving us our colour vision.

Answer 2

Its the same reason you have colours in the rainbow, its the reflection of light reflecting from the sea, same reason that when you when you make a fine mist of watter on a sunny day you see a mini rainbow, and thats why you only see a rainbow when its raining but sunny

Something to do with reflection of light!! It is not always blue though! At night it is black and at dusk and dawn it can sometimes be red, orange, yellow!!

Answer 4

Gases in our atmosphere reflect other colors of the visible spectrum, so blue is shown.
