Wave Interference https://phet.colorado.edu/sims/html/wave-interference/latest/wave-interference_en.html In your lab report, be sure to show calculations. And include screenshots. Part 1. Double Slit Interference In the pictures on the last page, the rays are emitted in all directions from the slits, but let's concentrate on the rays that are emitted in a direction o toward a distant screen (0 measured from the normal to the barrier). One of these rays has further to travel to reach the screen, and the path difference is given by d sin 0. 4 K to screen d sin 0 Small angle simplification: If o is small (
