If (3 2 6) are the Miller indices of a plane, the intercepts made by the plane on the three crystallographic axes are

Detailed Solution: Question 9

 For Miller indices (h, k, l) the intercepts are (a/h, b/k, c/l). For (3, 2, 6) this gives (a/3, b/2, c/6). Multiplying each intercept by 6 yields (2a, 3b, c), which corresponds to option b.

Test: Structural of Metals & Alloys - 2 - Question 10

In a simple cubic lattice d100: d110: d111 is
where d is interpianer spacing.

Detailed Solution: Question 10

Correct Answer :- D

Explanation : d100 = a/(12 + 02 + 02)1/2

= a

d110 = a/(12 + 12+ 02)1/2

= a/(2)1/2

d111 = a/(12 + 12 + 12)1/2

= a/(3)1/2

d100 : d110 : d111 = a : a/(2)1/2 : a/(3)1/2

= 61/2 : 31/2 : 21/2
