Objective: To analyze and conclude our lab Success criteria: Draw ray diagrams and verify the lens equation
Thin lens equation magnification equation = 1. d o d i f M = - d i = h i.. d o h o
Lab: images formed by a converging lens
Find the focal length
Find image distances for 5 object positions
Is the lens equation valid?
Analysis #11 on a blank paper: –Draw ray diagrams for each position –Use 3 cm for the focal point #14 label each drawing –Spotlight –Copy camera –Magnifying glass –35mm camera –Slide projector
Out: Why did you use the light from the tree outside to find your focal length?
