Why is the sky always red after rain?
That's because rain has a stronger reflection on the red light in the sun, and this red phenomenon basically appears in the evening, and the refraction angle of light is also one of the reasons for this phenomenon, just as the sky we usually see is blue, because the dust particles in the air have a stronger reflection on blue light.
