Question

how to sketch the following?:Sketch ray diagrams for a spherical convex lens with objects at the following distances. (Submit a file with a maximum size of 1 MB.)Do > 2f2f > Do > fDo < f

Answer 1

1) Do > 2f

Do means object distance

2f means 2 x focal length

2 x focal length = radius of curvature

When an object is placed beyond the radius of curvature, a real image is formed between the radius of curvature and focus. The image size is reduced. The sketch is shown below
