Why sun emerge flat throughout sunrise and sunset
Briefly explain the reason why does sun emerge flat throughout sunrise and sunset?
Expert
The sun rays have to travel via a larger atmospheric distance. Most of the blue light and shorter wave lengths are eliminated through scattering. Only red color, that is least scattered is received by our eyes and emerge to come from sun. Therefore the appearance of sun at sunset or sunrise appears approximately flat.
