Date | Reading for lab | Topic description |
Lab 1 January 20 |
Introduction — including computer portions on Excel and the World Wide Web. Visual Angle. Calculating the visual angle of your thumbnail at arm’s length and then using it.Visual Angle PowerpointVisual Angle Excel Constant Angle to manipulate (BROKEN LINK) in Geometer’s Sketchpad program (GSP) |
Visual Angle.Assignment: Calculate the visual angle of your thumb at arm’s length, the moon, the sun, and your computer screen at a comfortable viewing distance.
Review visual angle data; What does it mean? What does the comparison between the sun and moon imply? Look at visual angle of objects in hallway at different distances |
