This 15-minute video is the second in a series on how light interacts with lenses to form images. Through narrated demonstrations and animated models, the video takes a deep look into light refraction by convex lenses. It also instructs on how to draw ray diagrams and use them to determine the size, position, and nature of images formed through convex lenses. This video is one of a four-part series on light and images, developed to promote deep understanding of light and matter interactions through use of narration, animation, and video clips depicting phenomena in action.
