WRONG!!
Quite the reverse…when the sea looks blue it is because of the blue light from the sky (after all it looks grey when the sky is totally cloudy and black at night!). But why is the sky blue?…for the same reason that the sunset is red!!!
As the light from the Sun travels through our atmosphere some gets scattered in all directions. As it happens, the shorter wavelengths scatter more than longer ones.
WHITE LIGHT from the Sun is made up of the colours of the rainbow…the colours of the white light "spectrum" as seen when light goes through a prism. What many people do not know is that the different colours are different wavelengths (or different frequencies). Violet (usually called the "blue end" of the spectrum) light has the shortest wavelength while red is nearly double the size. So the light comes from the Sun…a mixture of all these colours…..as it goes through the air where there are lots of tiny particles the shorter (blue) scatters out…so coming down and up from the air is blue light (yes it looks blue from space too) and what is left over carries on as RED light to make someone a nice sunset.
