For a cubic crystal structure which one of the following relations indicating the cell characteristics is correct?
Options
(a) a ≠ b ≠ c and α = β = γ = 90⁰
(b) a = b = c and α ≠ β ≠ γ = 90⁰
(c) a = b = c and α = β = γ = 90⁰
(d) a ≠ b ≠ c and α ≠ β and γ ≠ 90⁰
Correct Answer:
a = b = c and α = β = γ = 90⁰
Explanation:
For a cubic crystal, a = b = c and α = β = γ = 90⁰
