Question

give reason why we can see the sun about 2 minutes before the actual sunrise and two minutes after actual sunset​

Answer 1

Answer:

Reason: Atmospheric Refraction

Explanation:

The sun is visible to us about two minutes before the actual sunrise and about two minutes after sunset because of atmospheric refraction. When the sun is slightly below the horizon, the sun rays travel from less dense to more dense air and hence bends as it bends towards the normal each time, making it appear raised.

Answer 2

Answer+Explanation:

The sun can be seen two minutes before actual sunrise and two minutes after the actual sunset.

It is because of ' atmospheric refraction '

Because of this refraction , when sun get actually sets or sun were before the get rise... we can see it late and early as apparent position of sun ... we know our atmosphere contains dust particles and have different layers with different density... So the light of sun get refracted...

And it will be seen two minutes early or after .....
