Teacher Resources

The Physics Classroom has been devoted to helping students, teachers, and classrooms since the 1990s. We are as passionate about that mission now as we have ever been. If you are a teacher of Physics or Physical Science, we encourage you to use our Video Tutorial with your students. And we also encourage you to consider the use of other resources on our website that coordinate with the video. We have listed a few below to help you get started.


Physics Interactives, Light and Color: Young's Experiment

After understanding two-point source interference, the next logical step is to do Young's Experiment. This Task-Tracker compatible simulation provides students an environment to practice using Young's Equation to measure the wavelength of light. Feedback is immediate. Students have multiple opportunities to correct their errors.

Science Reasoning Center, Light Waves: Models of Light

This interactive exercise probes the dual nature of light. The success and failure of the wave model of light and the particle model of light to explain reflection, diffraction, interference,and the photoelectric effect are explored. Use it with or without a Task Tracker account.
