일반물리학 2 — Diffraction: Problem 2

2 In Fig. 36-30, an x-ray beam of wavelengths from 80.0 pm to 140 pm is incident at \(\theta = 45.0^\circ\) to a family of reflecting planes with spacing \(d = 300\text{ pm}\). What are the (a) longest wavelength \(\lambda\) and (b) associated order number \(m\) and the (c) shortest \(\lambda\) and (d) associated \(m\) of the intensity maxima in the diffraction of the beam?
