Q.NO.1 why the light is reflected in air​

Answer 1

Explanation:

Air does reflect light. That's how mirages come into being. Granted, this reflection takes place at relatively low angles of incidence and at a relatively sharp boundary between air layers of different temperature (and thus density and thus index of refraction), but it certainly happens.

Answer 2

Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface.
