Types of Images Formed by a Converging Lens

A converging lens is a lens that is thicker in the middle and thinner at the edges. It is also known as a convex lens. When light passes through a converging lens, it can form different types of images depending on the position of the object relative to the lens.

The types of images that can be formed by a converging lens are:

1. Real, Inverted, and Enlarged Image: When the object is placed beyond the focal point of the lens, a real image is formed on the opposite side of the lens. The image is inverted (upside down) and larger in size compared to the object. This is the most common type of image formed by a converging lens.

2. Real, Inverted, and Same Size Image: When the object is placed at the focal point of the lens, a real image is formed at infinity. The image is inverted and the same size as the object. This means that the image is not magnified or reduced in size.

3. Real, Inverted, and Reduced Image: When the object is placed between the focal point and the lens, a real image is formed on the same side as the object. The image is inverted and smaller in size compared to the object. This type of image is formed when the object is closer to the lens than the focal point.

4. No Image: When the object is placed inside the focal point of the lens, no real image is formed. Instead, a virtual image is formed on the same side as the object. The virtual image is upright (not inverted) and larger in size compared to the object. However, this virtual image cannot be projected onto a screen and is not considered a "real" image.

Based on the given options, the type of image that cannot be obtained using a converging lens in air on a screen is Option 1: Imaginary, Direct, and Enlarged Image. This is because a converging lens cannot produce imaginary images. Imaginary images are formed when the light rays do not actually converge to a point and do not intersect. In the case of a converging lens, the light rays always converge to form a real image.
