Chapter 9.5, Problem 44PPS

To determine

To state whether the given crystals has the plane symmetry and/or axis symmetry. If so state the magnitude of the symmetry.

Answer to Problem 44PPS

Both. Magnitude ${90}^{\circ }$ degrees.

Explanation of Solution

Given:

The given crystal figure of orthorhombic is as follows-

  

Calculation:

A rotation of ${90}^{\circ }$ degree along the top of orthorhombic crystal would map the orthorhombic onto itself this means the given figure has the axis symmetry and it also has plane symmetry.

Magnitude ${90}^{\circ }$ degrees.
