This 14-minute video is the third in a series on how light interacts with lenses to form images. Video 3 demonstrates how to draw a ray diagram when an object is placed at any position in front of a convex lens. In addition to narrated demonstrations, the resource shows animated ray diagrams alongside video insets depicting the actual phenomenon. The professional scripting, production, and editing serve to provide a much deeper learner experience than traditional lecture demonstrations. This video is one of a four-part series on light and images, developed to promote deep understanding of light and matter interactions. See Related Materials for links to the companion videos.

Editor's Note:This resource would be a good choice for a flipped lesson. How does a magnifying glass work? Does it produce a real or virtual image? How do we connect this with the object's position on the principal axis? How do we calculate magnification of a lens? The video does a remarkably nice job of incorporating animation, video, and narration to answer these questions.

4. The Physical Setting
3-5: 4F/E3. Light travels and tends to maintain its direction of motion until it interacts with an object or material. Light can be absorbed, redirected, bounced back, or allowed to pass through.
6-8: 4F/M5. Human eyes respond to only a narrow range of wavelengths of electromagnetic waves-visible light. Differences of wavelength within that range are perceived as differences of color.
6-8: 4F/M8. There are a great variety of electromagnetic waves: radio waves, microwaves, infrared waves, visible light, ultraviolet rays, X-rays, and gamma rays. These wavelengths vary from radio waves, the longest, to gamma rays, the shortest.
Next Generation Science Standards
Disciplinary Core Ideas (K-12)
Electromagnetic Radiation (PS4.B)
When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object's material and the frequency (color) of the light. (6-8)
The path that light travels can be traced as straight lines, except at surfaces between different transparent materials (e.g., air and water, air and glass) where the light path bends. (6-8)
Information Technologies and Instrumentation (PS4.C)
Multiple technologies based on the understanding of waves and their interactions with matter are part of everyday experiences in the modern world (e.g., medical imaging, communications, scanners) and in scientific research. They are essential tools for producing, transmitting, and capturing signals and for storing and interpreting the information contained in them. (9-12)
Crosscutting Concepts (K-12)
Cause and Effect (K-12)
Cause and effect relationships may be used to predict phenomena in natural or designed systems. (6-8)
Systems and System Models (K-12)
Models can be used to represent systems and their interactions—such as inputs, processes and outputs— and energy, matter, and information flows within systems. (6-8)
