일반물리학 2 — Diffraction: Problem 22

22 Figure 36-33 gives \(\alpha\) versus the sine of the angle \(\theta\) in a single-slit diffraction experiment using light of wavelength 610 nm. The vertical axis scale is set by \(\alpha_s = 24 \text{ rad}\). What are (a) the slit width, (b) the total number of diffraction minima in the pattern (count them on both sides of the center of the diffraction pattern), (c) the least angle for a minimum, and (d) the greatest angle for a minimum?
