# Why does refraction cause an object to seem closer than it actually is?

Announcements Posted on
Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. For example if there is a pool why does the pool seem shallower or if you drop a coin in a pool why does the coin seem larger? I know refraction is when a light wave bends towards the normal when it enters another medium of another density causing the light wave to change speed. So why does refraction cause this to happen, i want a full detailed explanation please.

Hope this figure gives an insight.

Can you please explain this in writing, i understand the image kind of but i dont understand exactly why do we see as closer to us why the bending of the light ray make us see the object us being closer to us. Can you give me a sentence explaining this. Sorry if i sound dumb and dont understand this concept, but im one of these people that always needs to know in full detail why something happens.

The rays of light coming from the bottom of the container is refracted by the water and form a virtual image of the base some height above where the base actually is thus misleading the observer.
