Hello steemians . Everyone has noticed that during evening tine or morning the sky seems to be orange Why?
>Answer
Because during day time the sun is at overhead then sun travel less distance causes less dispersion but during morning and evening the wavelength of the sunlight increase as the light travels long path then wavelength increase the colour also change 
As the colours having more wavelength are at right part and less wavelength are at left so we see the orange as red is hard to see and at noon we see blue but in actual the colour is voilent
