Answer 1

Answer:

Refraction of light...............

Answer 2

Answer:

and) c. Refraction of light

Step-by-step explanation:

A star appears slightly higher(above)than its actual position in the sky. ... Air higher up in the sky is rarer but that nearer the earth's surface is denser. So, as the light from a star comes down, the dense air bends the light more. Due to this refraction of star's light, the star appears to be at a higher position
