Suppose you had the same laser and diffraction grating from the previous question but now you had a flat detection screen. You want to use this set up to measure the displacement due to small vibrations of the detection screen. (The vibrations cause the screen to move closer and farther from the grating.) A. Describe how you would do measurements for this experiment to determine the displacement of the detection screen.
