Write the position of object and image. (Real image formed by a convex lens )
Answers
Answer:
Image Characteristics for a Convex Lens
The table shows what happens to the image as an object is brought from infinity toward a convex lens.
Object Position Image Position Image Characteristics
At infinity At focal point Image is a point
Moving toward 2F Moving from F toward 2F Increasing in size, real, inverted, smaller than object
At 2F At 2F Real, inverted, same size as object
Moving from 2F toward F Moving from 2F toward infinity Real, inverted, larger than the object
At F At infinity Infinitely big
Moving from F toward lens Moving from -infinity toward lens Decreasing in size, virtual, upright, larger than the object
As long as the image as real the ray diagram is reversible. An object at point A creates an image at point B, while an object at point B creates an image at point A.
