Mesmerizing Saturday- it’s hard to imagine a blue sunset!
Toh HL explains why sunsets and sunrises are red and not blue!
So round, spectacular, and mesmerizing sometimes, shy, bashful behind the clouds often ordinary, the reddish blaze disappearing as if in a hurry for another appointment? Rayleigh scattering is the phenomenon for during sunsets or sunrises, sunlight has to penetrate a thicker layer of dust and water vapour in the atmosphere. The red end of the colour spectrum is scattered less compared to the blue end Hence, red reaches our eyes easily as it has a shorter wavelength than blue It's hard to imagine a blue sunset!
