The distance between two successive atomic planes of a calcite crystal is 0.3 nm. The minimum angle for Brag scattering of 0.3 Å X-rays will be
Text Solution
Verified by ExpertsThe correct answer is:
C
For constructive interference, we must have
2d sin θ = n λ
or sin θ = 
= 
= 0.05RAD
= 
= 2.86°
2d sin θ = n λ
sin θ = 
= 
= 0.05 = 
= 2.86°
