d.) Based on your conclusion, reducing the screen distance will cause the pattern to contract (decrease y). expand (increase y). remain the same. Reduce the slit separation d to approximately 900 nm. Doing so makes the slit separation smaller than it was in the initial setup. Describe the result and state whether or not it is consistent with your conclusion. Return the slits to a separation of 1750 run so that the initial setup is restored Use the tape measure to measure the barrier to screen distance. Record position. :1 =
