Change in Position, Nature and Size of Image Formed by Replacing Convex Lens with Concave Lens of Same Focal Length
Ray Diagram for Convex Lens
A convex lens is a converging lens which forms a real and inverted image when the object is placed beyond its focal length and a virtual and erect image when the object is placed within its focal length. The ray diagram for a convex lens is as follows:
Ray Diagram for Concave Lens
A concave lens is a diverging lens which always forms a virtual, erect, and diminished image. The ray diagram for a concave lens is as follows:
Difference in Image Formation
When a convex lens is replaced by a concave lens of the same focal length, there is a significant difference in the formation of the image. The image formed by the concave lens is always virtual, erect, and diminished, whereas the image formed by the convex lens can be real or virtual, inverted or erect, and magnified or diminished depending on the position of the object.
Effect on Position of Image
When a convex lens is replaced by a concave lens of the same focal length, the position of the image also changes. In the case of a convex lens, the position of the image depends on the position of the object, whereas in the case of a concave lens, the image is always formed on the same side as the object and closer to the lens.
Effect on Size of Image
The size of the image formed by a concave lens is always smaller than the size of the object, whereas the size of the image formed by a convex lens can be either larger or smaller than the size of the object depending on the position of the object.
Conclusion
To sum up, when a convex lens is replaced by a concave lens of the same focal length, the nature of the image formed changes from real/inverted or virtual/erect to always virtual/erect. The position of the image changes from being position-dependent to always being on the same side as the object and closer to the lens. The size of the image formed by the concave lens is always smaller than the size of the object, whereas the size of the image formed by the convex lens can be either larger or smaller than the size of the object depending on the position of the object.
