The image formed by a slide projector is usually:

Options

A. real, inverted and diminished
B. real, inverted and magnified
C. virtual, upright and magnified
D. virtual, inverted and diminished

Explanation

To determine the characteristics of the image formed by a slide projector, we can analyze the situation step by step:

### Step-by-Step Solution:

1. **Understanding the Slide Projector**:
- A slide projector is an optical device that uses a light source and a lens system to project images onto a screen.

2. **Type of Lens Used**:
- Slide projectors typically use a **convex lens**. Convex lenses are known for their ability to converge light rays and form real images.

3. **Position of the Object**:
- In a slide projector, the object (the slide) is placed between the focal point (F) and twice the focal length (2F) of the lens. This positioning is crucial for the type of image formed.

4. **Image Formation**:
- When an object is placed between F and 2F in front of a convex lens, the lens forms a **real image** on the opposite side of the lens. This image is formed because the light rays converge after passing through the lens.

5. **Orientation of the Image**:
- The image formed by a convex lens when the object is placed in this manner is **inverted**. This means that the top of the object appears at the bottom of the image and vice versa.

6. **Size of the Image**:
- The image formed is also **magnified**. This means that the image appears larger than the actual object. The degree of magnification depends on the distance of the object from the lens.

7. **Conclusion**:
- Based on the analysis, the characteristics of the image formed by a slide projector are: **real, inverted, and magnified**.

### Final Answer:
The image formed by a slide projector is usually **real, inverted, and magnified**.
