This 15-minute video is the first in a series on how light interacts with lenses to form images. This video explores the nature of images formed by the human eye, a magnifying glass, a pinhole camera, a plane mirror, and concave mirror. It goes into detail to explain both real and virtual images and identify where these phenomena occur in everyday experience. The professional scripting, videography, production, and editing help to ensure that beginners can visualize the complex processes underlying image formation. The pacing is suitable for middle school, but could also be a short refresher for the high school classroom.

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, animated modeling, and video clips depicting phenomena in action.

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)
  • Systems may interact with other systems; they may have sub-systems and be a part of larger complex systems. (6-8)
  • 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)
Science is a Human Endeavor (3-12)
  • Advances in technology influence the progress of science and science has influenced advances in technology. (6-8)

AAAS Benchmark Alignments (2008 Version)

4. The Physical Setting

4F. Motion
  • 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.

Is Associated With Light and Lenses: Images and Convex Lenses

This is Part 3 of the Light and Lenses series. It deeply explores how ray diagrams can be used to determine the position and size of images produced by convex lenses and demonstrates how to calculate magnification in a lens.
