explain advance sunlight and delayed sunset
Answers
Answer:
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.

I hope its help you

Answer:
Solution. 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.
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.
The path of the rays of light comig f=coming from the distant star goes on varying due to atmospheric refraction slightly. Thus, apparent position of the star fluctuates and the amount of star light entering the eye flickers giving the twinkling effect.
Why is the sun visible to us 2 minutes before sunset?
Why is the sun visible to us 2 minutes before sunset?When the light rays passes through the atmosphere having layers of different densities and refractive indices, then atmospheric refractioon takes place. ... Due to continuous refraction of light rays at each layer, it follows a curved path and reaches the eye of the observer. As a result , we can see the sun 2 mins.
