Description
The activity involves building a simple pinhole viewer and using colored lights to investigate how light travels. Students observe how light passes through the small hole and forms an image on the wax-paper screen. They discover that light travels in straight lines and that the image appears upside down and reversed because of how the light rays pass through the pinhole. The activity also encourages students to experiment with the viewer, change its design, observe different light sources, and develop new questions.
