Differentiate between the reflection of light from a plane mirror and that from a plane sheet of paper.

Explanation

To differentiate between the reflection of light from a plane mirror and that from a plane sheet of paper, we can follow these steps:

### Step 1: Understand the Surface Characteristics
- A plane mirror has a **smooth surface** at both macroscopic and microscopic levels.
- A plane sheet of paper has a **rough surface** at the microscopic level.

### Step 2: Identify the Type of Reflection
- The reflection of light from a plane mirror is known as **regular reflection** (or specular reflection). This occurs because the smooth surface allows light rays to reflect at the same angle they hit the surface, maintaining the image's clarity.
