Atmospheric refraction

Vedclass · Answer

(C) The sun appears to rise about $2$ minutes before the actual sunrise and sets about $2$ minutes after the actual sunset due to atmospheric refraction.As sunlight enters the Earth's atmosphere,it passes through layers of air with varying densities.This causes the light rays to bend (refract) towards the normal.Due to this bending,the sun appears to be at a higher position in the sky than it actually is,causing the observer to see the sun before it crosses the horizon.
