Red Sky Phenomenon
Red sky in the evening towards night is a beautiful optical phenomenon, which occurs due to the refraction of sunlight through the atmosphere, and can be associated with clear and stable weather.
Solar scattering, when the sun rises or sets, sunlight travels a greater distance through the atmosphere. Blue light is scattered more than red light, so red light is more dominant and makes the sky appear red or orange.
Particles such as dust, pollution or smoke, can scatter sunlight and strengthen the red color in the sky.
Greetings compact always.
