Now, select the Slits simulation at the bottom of the screen, and Light (red) for the type of wave, as before. Also, make sure there is a barrier with one slit, and use the tape measure as well as the slider bar below the slit to place it roughly 1290 nm away from the light source. Adjust the slit width to 300 nm. Finally, select the start button at the source location to begin producing the waves. Which statement best describes how the intensity of the wave depends on position along the screen? Selecting the Intensity checkbox will show a plot of the intensity on the screen.
