Answer 2

Answer:

Refraction is the right answer.

Explanation:

Light waves are not constantly travelling in a uninterrupted route. Meanwhile it moves through a channel of a complex refractive index, the waves will vary. This aspect is termed as refraction. The density of wind in the environment of the earth has many fluctuation depending on the altitude. As the refractive index modifies with the density of the means, light waves moving within the atmosphere of the Earth also encounter refraction. Due to this Sun arrives elliptical near the horizon.
