Calculate the longest wavelength, Physics

Assignment Help:

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
