My physics textbook has a diagram that illustrates Apparent Depth... but I can't understand it. Specifically, why does the image appear where it is (at apparent depth)? I understand that as the light from the object moves from water to air, refraction occurs... but I'm thinking, shouldn't the angle at which the person's eyes recieve the light go all the way to the bottom of the pool or something? It seems as if the light is still reaching the person's eyes the same horizontal distance from the object? Is that true? So then, is the the following image true for when the light will bend towards the normal, where the end of the yellow line to the top of the surface will be apparant depth? (would explain increased apparant depth)... TiA.
