See an object clearly in fluid like water

  1. Sep 5, 2014 #1
    Why do we able to see an object clearly in fluid like water, even if the object is doing a slight movement we are able to see from long distance,for examle in the fish aquerium.

    My effort-
    I think so that this is due to refraction of the light or due to some natural property of liquid.

    Refreaction is just a BENDING of the light rays and has nothing to do with why we can see things in water, unless you are talking specifically about where you are looking at a sharp angle to the water. Is that what you mean?

    TRANSPARENCY is the reason we are able to see things in "clear" fluids such as water and glass and air.
