Physical Science 20 - May 13

Today in class students spent time drawing ray diagrams for lenses.  They followed instructions outlined on a handout called Finding the Image Graphically - Ray Diagrams for Lenses.  These instructions guided students through how to draw these diagrams.  It is similar to the diagrams we drew for curved mirrors and there are many analogies to it.  Students then spent the remainder of the class working on Assignment 3.2.  This will be handed in Monday.  We will then learn how to find the image mathematically.
