The final image produced by a simple microscope is :

Options

A. Real and inverted
B. Real and erect
C. Virtual and erect
D. Virtual and inverted

Answer

To determine the nature of the final image produced by a simple microscope, we can follow these steps:

### Step 1: Understand the Basic Function of a Simple Microscope
A simple microscope is essentially a convex lens that is used to magnify small objects. The lens creates a larger image of an object that is placed close to it.

**Hint:** Remember that a simple microscope uses a convex lens to magnify objects.

### Step 2: Position of the Object
For a simple microscope to function effectively, the object must be placed within the focal length of the lens. This means that the object is located between the focal point (F) and the lens itself.

**Hint:** The object must be placed between the focal point and the lens for magnification to occur.

### Step 3: Ray Diagram Analysis
When we draw a ray diagram for this setup:
- One ray from the object travels parallel to the principal axis and refracts through the focal point on the opposite side.
- Another ray passes through the center of the lens and continues in a straight line.

These rays diverge after passing through the lens.

**Hint:** Sketching a ray diagram helps visualize how light behaves when passing through the lens.

### Step 4: Image Formation
The rays diverging from the lens appear to originate from a point behind the lens. This means the image formed is virtual, as it cannot be projected onto a screen.

**Hint:** If the rays diverge, the image is virtual and cannot be captured on a screen.

### Step 5: Characteristics of the Image
The image formed by a simple microscope is:
- Virtual (since it cannot be projected)
- Erect (the image maintains the same orientation as the object)
- Magnified (the size of the image is greater than that of the object)

**Hint:** Remember the characteristics of the image: virtual, erect, and magnified.

### Conclusion
Thus, the final image produced by a simple microscope is virtual, erect, and magnified.

**Final Answer:** The final image produced by a simple microscope is virtual and erect.
