This site is designed as a convenient location for our visitors to view the various Java tutorials that we have constructed to aid in teaching concepts in light and color. This tutorial allows students to visit our Java development laboratory at the National High Magnetic Field Laboratory where these tutorial-applets are created. Visitors can adjust the slit width and the wavelength of light to discover how these variables affect optical diffraction. Visitors can adjust the distance between the slits and the wavelength of light to discover how these variables affect optical diffraction and interference of the diffracted light waves. Well you can with this tutorial that allows you to move the wave around in three-dimensional space.
Visitors can also adjust the wavelength to see how that affects the wave.
Visitors can choose between the three phenomena and see the various states that excited electrons pass through in returning to the ground state. This tutorial permits visitors to vary the photon wavelength to propel the electrons into various energy levels. Interference - Interference between two light waves is an amazing phenomenon that is often seen in soap bubbles with the wide color spectrum that they reflect. This tutorial allows students to add two light waves together and view the result. The frequency, wavelength, and amplitude of the waves are variable, allowing the production of practically all combinations resulting from interference between two waves.
