1.	Following three planes `(P_(1), P_(2), P_(3))` in an fcc unit cell are shown in the figure below. Consider the following statements and choose the correct option/options that follow: A. `P_(1)` contains no three dimensional voids .B. `P_(2)` contains only octahedral voids.C. `P_(3)` contains both octahedral and tetrahedral voids .D. `P_(3)` contains tetrahedral voids .
Answer» Correct Answer - A::B::C::D A `P_(1)` represents one of the clo-packed layer having triangular voids only. B. `P_(2)` contains location of `Ovs` (edge centers of unit cell). C. `P_(3)` contains 3OVs locations (one at body center and two at edge center. Also, plane `P_(3)` contains the body diagonals, hence it contains TVs location (TVs lie at body diagonal).
