Solid State Question 272
Question: In Bragg’s X-ray diffraction studies. 100 pm X-ray second order diffraction at glancing angle of $ 30{}^\circ $ . Its interplanar spacing will be
Options:
A) 200 pm
B) 150 pm.
C) 100 pm
D) 144 pm
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ n\lambda =2d\sin \theta $
$ 2\times 100=2\times d\times 1/2 $ ( $ \sin 30{}^\circ =1/2 $ ) $ d=200pm $
