Sunset is red because at that time the light coming from the sun has to travel:(a) lesser thickness of earth's atmosphere (b) greater thickness of earth's atmosphere(c) varying thickness of earth's atmosphere (d) along the horizon
(b) greater thickness of the earth's atmosphere
Explanation
The sun appears red at sunrise and at sunset because, at that time, the sun is near the horizon and, therefore, sunlight has to travel through a greater thickness of the earth's atmosphere. Due to this most of the blue colour present in the sunlight scattered out and away from the line of sight, leaving mainly the red colour in the direct beam of sunlight that reaches our eyes.
