What is atmospheric refraction? Explain advance Sunrise and delayed Sunset?
Answers
Answer:
okay bro
Explanation:
Advanced sunrise and delayed sunset are phenomena caused due to atmospheric refraction. In this the Sun appears to rise early by 2 minutes and set late by 2 minutes. The diagram below shows this phenomenon. When the rays from the Sun hit the atmosphere they get refracted.
Explanation:
When light goes from one medium to another medium having different optical densities, then refraction of light rays (or bending of light rays) takes place. The refraction of light caused by the earth's atmosphere (having air layers of varying optical densities) is called atmospheric refraction
The Sun appears about two minutes before the actual sunrise and this phenomenon is known as advance sunrise. The Sun remains visible about two minutes after the actual sunset and this phenomenon is known as delayed sunset. The advance sunrise and delayed sunset happen due to atmospheric refraction
