State the type of crystal defects shown by AgBr.

Explanation

To determine the types of crystal defects shown by AgBr (Silver Bromide), we can analyze the characteristics of the crystal structure and the nature of the defects.

### Step-by-Step Solution:

1. **Understanding Crystal Defects**:
- Crystal defects are irregularities in the crystal lattice that can affect the properties of the material. The two main types of point defects are Schottky defects and Frenkel defects.

2. **Identifying Schottky Defect**:
