A) 2, 3, 1
B) 1, 2, 4
C) 3, 2, 6
D) 1, 2, 3
Correct Answer: C
Solution :
For 2a, 3b, c the Miller indices is calculated as: \[h=\frac{a}{intercept\text{ }of\text{ }plane\text{ }attach\text{ }from\text{ }x-axis}\] \[=\frac{a}{2a}=\frac{1}{2}\] \[k=\frac{b}{intercept\text{ }of\text{ }plane\text{ }attach\text{ }from\text{ }y-axis}\] \[=\frac{b}{3b}=\frac{1}{3}\] \[l=\frac{c}{intercept\text{ }of\text{ }plane\text{ }attach\text{ }from\text{ }z-axis}\] \[=\frac{c}{c}=\frac{1}{1}\] \[n:k:l=\frac{1}{2}:\frac{1}{3}:1\] \[=3:2:6\]
