Answer 1

Hola mate! here is your answer:

Solution:

Due to refraction the star appears higher then it actual position

Other examples are:-

• Sunshine and Sunset are delayed for 2 mins
• Pencil appears to be bent when Dipped in water
• Coin appears to be Raised when kept in Water

Answer 2

Answer:

The gradual change in the refractive index of different layers of the atmosphere due to the varying conditions of it causes atmospheric refraction. When starlight enters the atmosphere, it gets refracted continuously. The higher level of air acts as a rarer medium while the dense air near the surface of earth acts as a denser medium. So, the atmosphere bends the starlight towards the normal. As a result, the apparent position of star is slightly different from its actual position. Thus, star appears slightly higher (above) than its actual position in the sky.
