Light and Matter Interactions (The Activity)

Interactive, scaffolded model

Go To Activity

Follow the link above to start or download this activity.

This Activity Requires:

Java 1.5+ - Java 1.5+ is available for Windows, Linux, and Mac OS X 10.4 and greater. If you are using Mac OS X 10.3, you can download MW Version 1.3 and explore within it instead.

Test your system to see if it meets the requirements

Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.

Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

	Overview and Learning Objectives Students are introduced to the basic concepts of light, followed by several interactive simulations that model the interactions of light with matter. Students will be able to: • manipulate intensity and frequency of light, including adjusting intensity and seeing its effect on the heating of matter; • replicate in a model a beam of photons of particular intensity and energy; • describe two fates of light-matter interaction: passage through, or absorption and consequence by matter; • generate and read an absorption spectrum. return to top
