It was observed that when the distance between an object and a lens decreases, the size of the image increases. What is the nature of this lens? If you keep on decreasing the distance between the object and the lens, will you still able to obtain the image on the screen? Explain

Explanation

### Step-by-Step Solution:

1. **Identify the Lens Type**:
- When the distance between an object and a lens decreases, and the size of the image increases, we need to determine the type of lens. The lens that exhibits this behavior is a **convex lens**. Convex lenses converge light rays that pass through them, which results in a larger image as the object gets closer.

2. **Understanding Image Formation**:
- As the object approaches the lens, the image formed by a convex lens changes. Initially, when the object is beyond the focal point, a real and inverted image is formed. However, as the object moves closer to the lens and crosses the focal point, the image becomes larger and eventually turns into a virtual image.
