Identify the lens which exhibits the following characterstics of image virtual, erect and diminished

Options

A. Convex lens
B. Concave lens
C. Plano convex lens
D. Concavo convex lens

Explanation

To solve the question, we need to identify the type of lens that produces a virtual, erect, and diminished image. Let's break it down step by step:

### Step 1: Understand the characteristics of the image
- **Virtual Image**: This type of image cannot be projected on a screen. It appears to be located behind the lens.
- **Erect Image**: The image is upright, meaning it has the same orientation as the object.
- **Diminished Image**: The image is smaller than the object.

### Step 2: Identify the types of lenses
1. **Convex Lens**: This lens converges light rays and can produce both real and virtual images depending on the position of the object.
2. **Concave Lens**: This lens diverges light rays and always produces virtual images that are erect and diminished.
3. **Pleno Convex Lens**: This is a type of convex lens, which also can produce real and virtual images.
4. **Concave or Convex Lens**: This option is ambiguous and does not specify a particular lens type.

### Step 3: Analyze the options
- **Convex Lens**: Can produce virtual, erect, and diminished images, but only when the object is placed between the focal point and the lens.
- **Concave Lens**: Always produces virtual, erect, and diminished images regardless of the object position.
- **Pleno Convex Lens**: Similar to convex lens behavior.
- **Concave or Convex Lens**: Too vague to determine.

### Step 4: Conclusion
Based on the analysis, the lens that consistently produces a virtual, erect, and diminished image is the **Concave Lens**.

### Final Answer
The lens that exhibits the characteristics of a virtual, erect, and diminished image is the **Concave Lens**.
