Answer 2

Building an Image in a Converging Lens When the Object Distance is Less Than the Focal Length

When the object distance is less than the focal length of a converging lens, the image formed is virtual, upright, and located on the same side as the object. This is a unique scenario in optics and can be explained using the lens formula and the concept of virtual images.

Lens Formula: The lens formula relates the object distance (u), the image distance (v), and the focal length (f) of a lens. It is given by: \[ \frac{1}{f} = \frac{1}{v} + \frac{1}{u} \]

Image Formation: When the object distance (u) is less than the focal length (f) of a converging lens, the image distance (v) is negative, indicating that the image is formed on the same side as the object. The image is virtual, upright, and magnified.

Representation: To represent this scenario, we can use the lens equation and the characteristics of the image formed by a converging lens when the object is placed within the focal length.

The image formation in this case can be illustrated as follows: - The object is placed at a distance less than the focal length from the lens. - The rays of light from the object converge on the same side of the lens to form a virtual, upright, and magnified image.

This representation demonstrates the unique behavior of a converging lens when the object is positioned within the focal length.
