let's understand this concept by an activity
Put a coin at the bottom of a pot of glass or plastic or stainless steal. Keeping eyes on the coin move away slowly from pot till coin disappears. Now, ask your Friend to pour water carefully and slowly into pot, ensure that the coin should not displace from it's position. Are you able to see the coin again, now? you did not change your position, then ,how it become possible to see the coin?
It is due to refraction of light. According to fig 14.2 (b) when light rays from coin passes from water (denser medium) to air (rarer medium) then it bends away from the normal to the surface. When those refracted rays enter in our eyes, the coin appears to be situated above to it's actual position.
