Students will have fun exploring the EM Spectrum with this interactive tool developed at the Scripps Institution of Oceanography. Earthguide: Electromagnetic Spectrum Interactive.You can start with basic properties, or move directly into more complex concepts such as interference, group velocity, boundary collisions, constructive/destructive interference, diffraction, dispersion of light, and polarization. Each of the 33 simulations is ready to run on mobile devices and includes question sets to gauge student understanding. Here you’ll find an exemplary free collection of interactive simulations in eBook format to explore the physics of waves, authored by physics professor Kyle Forinash and Physlet Physics author Wolfgang Christian. Three opportunities are provided to get the correct answers for wavelength. Once students have determined the values of wavelength for the three lasers (red, green, and blue), they can check their answers. The information is then used in Young's equation to determine the wavelength of the laser light. Students make measurements of the slit separation distance, the slit-to-screen distance, and the band separation distance on the screen. This interactive from The Physics Classroom simulates a Young's Experiment set-up using laser light shining upon a double slit.
