In a single-slit experiment, red light, λ = 633 nm, shines through a single-slit aperture of diameter 0.10 mm. The graph in Figure 3 is the intensity of the diffraction pattern on a screen located a certain distance behind the aperture.
(a) Calculate the distance between the screen and the slit.
(b) Suppose the single-slit aperture is swapped out and replaced with a second single-slit aperture where the aperture is smaller. Would the width of the central peak (the middle of the pattern in Figure 3) increase, decrease, or stay the same? Briefly explain.
