A) \[0.575\,\overset{o}{\mathop{A}}\,\]
B) \[1.00\,\overset{o}{\mathop{A}}\,\]
C) \[2.00\,\overset{o}{\mathop{A}}\,\]
D) \[1.17\,\overset{o}{\mathop{A}}\,\]
Correct Answer: D
Solution :
[d] According to Braggs equation |
\[n=2\,\lambda =1\,\theta ={{60}^{o}}\,d=?\] |
\[2\times 1=2\times d\times \sin {{60}^{o}}\] |
\[2\times 1=2\times d\times \frac{\sqrt{3}}{2}\] |
\[d=\frac{2}{\sqrt{3}}=\frac{2}{1.7}=1.17\,{\AA}\] |
