A) \[1\overset{\text{o}}{\mathop{A}}\,\]
B) \[2\overset{\text{o}}{\mathop{A}}\,\]
C) \[2.5\overset{\text{o}}{\mathop{A}}\,\]
D) \[4\overset{\text{o}}{\mathop{A}}\,\]
Correct Answer: D
Solution :
Using Bragg's formula \[2d\sin \theta \,=\lambda \] Given, d = 2A For the maximum wavelength sin = 1 \[{{\lambda }_{\min }}\,=2d=2\times 2\overset{\text{o}}{\mathop{\text{A}}}\,=4\overset{\text{o}}{\mathop{\text{A}}}\,\]You need to login to perform this action.
