Question

X-ray are incident normally on a crystal of lattice constant 0.6 nm . The first order reflection on diffraction from the crystal occurs at a glancing angle of $3 0^{\circ}$ . The wavelength of the X-ray used is $α$ nm. Fill $10 α$ in OMR sheet.

Answer:

6

Solution:

Bragg's law: $2 d sin θ = λ$

$λ = 2 \times 0.6 \times sin 3 0^{\circ} = 0.6 nm$

$10 α = 6$
