일반물리학 2 — Diffraction: Problem 17

17 Light of wavelength 620 nm passes through a double slit, yielding a diffraction pattern whose graph of intensity I versus angular position \(\theta\) is shown in Fig. 36-32. Calculate (a) the slit width and (b) the slit separation. (c) Verify the displayed intensities of the \(m = 1\) and \(m = 2\) interference fringes.
