In Gallilean telescope, the final image formed is

Options

A. real,erect and enlarged
B. virtual,erect and enlarged
C. real,inverted and enlarge
D. virtual,inverted and enlarged

Explanation

To solve the question regarding the final image formed by a Galilean telescope, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Galilean Telescope**:
- A Galilean telescope consists of two lenses: a convex lens as the objective and a concave lens as the eyepiece.
- It is designed to observe distant objects, typically used for terrestrial observations.

2. **Image Formation in the Telescope**:
- The convex lens (objective) forms a real, inverted image of the distant object.
- This real image is then used as the object for the concave lens (eyepiece).

3. **Characteristics of the Eyepiece**:
- The concave lens (eyepiece) produces a virtual image when the real image formed by the objective is placed within its focal length.
- The eyepiece magnifies this real image, making it appear larger to the observer.

4. **Final Image Characteristics**:
- The final image formed by the combination of the objective and eyepiece is virtual because it cannot be projected on a screen.
- It is also erect (upright) because the concave lens inverts the image formed by the convex lens.
- The final image is enlarged due to the magnifying effect of the eyepiece.

5. **Conclusion**:
- Therefore, the final image formed by a Galilean telescope is virtual, erect, and enlarged.

### Final Answer:
The final image formed in a Galilean telescope is **virtual, erect, and enlarged** (Option B).
