Q: What are the dimensions of a cubic crystal?
-
A
a =b ≠ c
-
B
a = b = c and α = β ≠ γ = 90
-
C
a = b = c and α = β = γ = 90
-
D
a ≠ b = c and α = β ≠ γ = 90
C
Answer:
C
Explanation:
A cubic crystal has three equal dimensions, a = b = c, and three angles, α = β = γ = 90. This is because a cubic crystal is a symmetrical structure, with each side of the cube being equal in length and each angle being equal in measure. The angles of a cube are all right angles, meaning that the measure of each angle is 90 degrees.
