Question

Why do stars seem higher than they actually are ? jisko aata hai wahi answer dena warna report kar dunga

Answer 1

Hey mate..

Here's your answer...

_____________________________________

This is due to ATMOSPHERIC REFRACTION.

The star light have to cross many layers of the
earth.Since the light continuously travels from
rarer to denser layer it constantly keeps bending
towards the normal.

Now since light always travels in a straight line .
so it seems that the star is little higher.

There is a pic to make you understand..

Here the light constantly bend but we can not see
because light travels in a straight line..

Answer 2

Stars are distant point size sources of light. To reach the observer's eye the lift ray had to pass through many layers of the atmosphere. There is a variation I the density of the air each time i.e. the light moves from a rarer to denser medium each time which makes it bend toward the normal. Therefore, the light reaches the observers eye on the form of a curve but we see in a straight line. So,we don't see the actual position of the star instead we see the apparent position of the star which is slightly higher.
