WM2.2 Laser and Screen

The screen that runs diagonally from the back wall to the first pillar on the north side of the lecture hall should be used. The laser is placed on a rolling table on the south side of the lecture hall, leveled by lab jacks and the slit plate is placed on a optical bench. The room lights must be turned off to see the diffraction pattern on the screen. The pattern seen on the screen is the intensity of the constructive and destructive waves. The best pattern consists of approximately five intensity peaks.
