Problem 37.7: Double slit
Please wait for the animation to completely load.
The animation shows the amplitude of a wave pattern. The greatest amplitude is represented by white, negative amplitudes are represented by black, and areas with zero amplitude are represented by gray. The mouse can be used to make coordinate measurements (position is given in nanometers). Restart. A double slit is hidden underneath the red bar in the animation. What is the slit separation?
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.
