Angle of reflection is ______

Options

A. Angle between the normal and the incident ray
B. Angle between the normal and the reflected ray
C. Angle between the incident ray and the reflected ray
D. Angle between the reflected ray and the surface of the mirror

Answer

To solve the question "Angle of reflection is ______," we need to understand the concept of reflection of light. Here’s a step-by-step breakdown:

### Step 1: Understand the Reflection of Light
When light hits a surface, it can either be absorbed or reflected. The angle at which it strikes the surface is called the angle of incidence, and the angle at which it reflects off the surface is called the angle of reflection.

### Step 2: Draw a Diagram
To visualize this, we can draw a diagram:
1. Draw a horizontal line to represent the reflecting surface.
2. Draw a vertical line perpendicular to the surface; this is called the normal line.
3. Draw an incoming light ray (incident ray) striking the surface at an angle.
4. Draw the reflected ray coming off the surface.

### Step 3: Label the Angles
- The angle between the incident ray and the normal line is called the angle of incidence (let's denote it as 'i').
- The angle between the reflected ray and the normal line is called the angle of reflection (let's denote it as 'r').

### Step 4: State the Law of Reflection
According to the law of reflection:
- The angle of incidence (i) is equal to the angle of reflection (r).
- Mathematically, this can be expressed as:
\[ i = r \]

### Step 5: Answer the Question
Thus, the angle of reflection is defined as the angle between the normal line and the reflected ray.

### Final Answer
The angle of reflection is the angle between the normal and the reflected ray.
