164 Geometric Optics 8.5 Eye Tank Front Front View Both View Side View Side The dark grey region is the part of the tank that can be seen from both the front and the side. You can actually see around the corner. This is really weird. So if you want a wider view from your window, you could just fill your room with water. Remember to also install the air tanks. § 8.5 Virtual Image Caused by Refraction Consider a shiny coin on the bottom of a swimming pool. Air Water The light comes up from the coin and out into the air. When the light comes out it spreads out more. This looks similar to the rays reflected from a mirror. This similarity leads one to wonder if there is a virtual image of the coin, that is, is there a place where all the rays appear to originate. The following diagram traces the rays back into the water.
8.5 Virtual Image Caused by Refraction 165 Air Water We see that they do not converge on a single point. The location of the image changes as you view it from different angles. When you get down low and view it from near the horizon the image is close to the surface of the water and also displaced horizontally from the object. As you move your view point upward the image moves away from you and deeper into the water. When you view from straight overhead the image is directly over the object and about 1/5 of the way up toward the surface. Air Water Image from horizon Image from 45° Image from directly above Object This is very different from the image in a flat mirror. The image in a flat mirror is in the same position, from any viewpoint in the room. ⊲ Problem 8.1 Consider the beam of light shown going through a prism made of glass with an index of refraction n.
