Answer 2

Answer:

1) When the rays of light from the sun enter the earth's atmosphere from outer space, they travel from a rarer medium to a denser medium. ... Hence, even when the sun is below the horizon while rising or setting , it's rays reach is due to refraction and it appears to be on the horizon.

2) It's also due to refraction of light . when light enters the glass block , it refracts towards the normal due to a change in density of medium and the object appears raised
