Phenomenon - fact or situation that is observed to exist or happen, especially one whose cause or explanation is in question
 * //Phenomenal Find //**


 * A. Fill a cylindrical container with water. **
 * B. Put the “E” behind the container and slowly move it back. Look through the container from the front and observe the “E” and arrow. **
 * 1. What is the phenomenon that you see? **
 * 2. Draw a before, during and after picture. **
 * 3. Draw an eye, container, and close arrow. **
 * Draw paths that the light takes from the arrow to the eye. **
 * 4. Draw an eye, container and far arrow. **
 * Draw paths that the light takes from the arrow to the eye. **

Before During After


 * //Light Paths //**** (SNB page 9/ Draw the following models) **
 * Drawings explaining what is happening are models. **
 * Models are often modified and improved. **
 * Compare your models in #3 and #4 above with these drawings. **
 * Solid lines are light rays. Dotted lines are how the object and light appears to be when seen through the container. **
 * When light enters a new medium perpendicularly, it will keep moving in the same direction. **
 * The line at the base of the arrow enters the container perpendicularly. **
 * Placing the base of the arrow where light enters perpendicularly allows me to simplify the drawing and draw half as many lines. **




 * Remember: The solid lines are real. The dotted lines are what we see. **


 * Remember: The solid lines are real. The dotted lines are what we see. **
 * The light reaching the container perpendicular comes from the center of the arrow. **
