Q Calculate the longest wavelength that can be analysed by a rock salt crystal of spacing d = 2.82 Ao in the first order.
Data: d = 2.82 Å = 2.82 × 10-10 m; n = 1 ; λmax = ?
Solution: For longest wavelength, (sin θ) max = 1
∴ 2d (sin θ) max = λmax
(Or) λmax = 2 ×2.82 × 10-10 ×1 / 1
λmax = 5.64 × 10-10 m
