Question

A star appears slightly higher than its actual position in the sky

Answer 1

It might the phenomenon of refraction of their light emitted with the atmosphere of earth.

Why do stars appear higher in the sky?

let us know in detail

Ans - As we know The atmospheric pressure decreases with altitude. At sea level, the atmospheric pressure is 1 atm.

At an altitude of 100km, it gets reduced to 3*10^-7 atm. As a result , the upper layers of atmosphere are optically rarer than the lower layers.

Thus, the atmosphere is optically denser near the earth and rarer at high altitudes.

the rays of light from a star Suffer refraction at each layer of the atmosphere and bend slightly towards the normal. thus, such a Ray of light from a star follows a curved path to reach the observer this Ray of light appears to come from the star at position x' the point x' is higher in the sky than the real position of the star.

Thus, the star appears to be higher in the sky
