Please wait for the animation to completely load.
The animation shows the interference (diffraction) pattern from light exiting a single slit located underneath the green strip (position is given in microns [10-6 meters]). In this animation, the greatest amplitude of the wave is represented by white, negative amplitudes are represented by black, and areas with zero amplitude are represented by gray. Restart. Determine the size of the slit.
This applet calculates seven frames and then runs continuously. For a large number of sources, or for very small wavelengths, this calculation can take some time, so let the applet finish calculating all seven frames.
