Question

The angle of incidence for a ray of light travelling from glass to liquid

Answer 1

If a ray of light hits the surface of a sheet of glass, some light will be reflected by the surface of the glass. However, much of the light will pass through the glass, because glass is transparent.

Water affects light rays in a similar way. Some light will be reflected off the surface of the water, but much of the light will pass through the transparent water.
