Because when the white light splits into the rainbow in the upper atmosphere all the other colours are deflected away and the blue is deflected to where we can see it.
Nice one Nitheen, I should add Tyndall was an Irish scientist.
A research centre in Cork is named after him.
The sky is not blue. The sky diffracts more of blue wavelength than the other visible colors.
This is called the Tyndall effect. ( Tyndall effect is the phenomenon in which light is scattered by particles of matter in its path).
Hi llogk
thanks for this fabulous question
The sky is blue because of the way the Earth’s atmosphere scatters light from the sun. 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.
hope my answer is clear
thanks
