Question

The ratio of a number of rectangular planes and diagonal plane in a cubic unit cell is ____.

• A. $1:2$
• B. $3:1$
• C. $2:3$
• D. $3:4$

Answer 1

The correct option is A $1:2$

The ratio of rectangular plane and diagonal plane in cubic unit cell is $3:6$ i.e, $1:2$

There are 3 planes that lie parallel to the side of the cube,that these are rectangular planes.while 6 planes goes through opposite edges.And also there are diagonal planes.

And Hence, the ratio of rectangular plane and diagonal plane in cubic unit cell is $3:6$ i.e, $1:2$
