In a compound microscope the image produced by the objective is

Options

A. real enlarged and errect
B. real enlarged and inverted
C. Virtual enlarged and erect
D. Virtual, enlarged and inverted

Answer

To solve the question regarding the image produced by the objective in a compound microscope, we can follow these steps:

### Step 1: Understand the Components of a Compound Microscope
A compound microscope consists of two lenses: the objective lens and the eyepiece. The objective lens is responsible for forming the initial image of the object being viewed.

**Hint:** Recall that the objective lens is the first lens that light encounters in a microscope setup.

### Step 2: Identify the Image Characteristics
The image produced by the objective lens can be characterized by its orientation (inverted or erect), nature (real or virtual), and size (enlarged or reduced).

**Hint:** Remember that the orientation of the image is crucial in determining how the final image appears to the observer.

### Step 3: Draw a Ray Diagram
To visualize the image formation, draw a ray diagram. In this diagram:
- Draw the object (e.g., a small arrow).
- Draw the objective lens and indicate the focal points (F and 2F).
- Trace at least two rays from the top of the object through the lens to locate the image.

**Hint:** Use the principles of ray optics: one ray parallel to the principal axis passes through the focal point after refraction, and another ray passing through the center of the lens continues in a straight line.

### Step 4: Analyze the Image Formed
From the ray diagram:
- The image formed by the objective lens is located between the focal point (F) and twice the focal point (2F).
- The image is real (since it is formed on the opposite side of the lens) and inverted (as indicated by the orientation of the arrows in the diagram).

**Hint:** A real image is formed when the object is placed outside the focal length of the lens.

### Step 5: Determine the Size of the Image
The image produced by the objective lens is typically enlarged compared to the actual size of the object. This is a key feature of microscopes, allowing for detailed observation of small objects.

**Hint:** Consider how the distance of the object from the lens affects the size of the image produced.

### Conclusion
Based on the analysis, the image produced by the objective lens in a compound microscope is:
- Real
- Inverted
- Enlarged

Thus, the correct answer is that the image produced by the objective lens in a compound microscope is real and inverted.

**Final Answer:** The image produced by the objective in a compound microscope is real, inverted, and enlarged.
