What is regular and diffused reflection? Give the diagram.

Explanation

### Step-by-Step Solution

**Step 1: Understanding Regular Reflection**
- Regular reflection occurs on smooth surfaces, such as mirrors or calm water. When parallel rays of light hit a smooth surface, they reflect off in parallel directions.
- **Diagram for Regular Reflection**:
- Draw a smooth surface (like a mirror).
- Illustrate several parallel incoming rays of light striking the surface.
- Show the reflected rays also parallel to each other, indicating that they maintain the same direction after reflection.
