ACTIVITY TO DETERMINE FOCAL LENGTH USING DISTANT OBJECT AND EXPERIMENT TO STUDY THE RELATIONSHIP BETWEEN u and v.

 Before entering the lab to carry out activity and experiments, you must do pre-lab. So here are a few things to help you prepare. Must read till the end.

Video of activity to determine focal length using distant object and experiment to find the relationship between u and v. Students can watch the video to get some ideas of what you are going to do in the lab later. 


Example report: Experiment to investigate the relationship between distance of object, u and distance of image, v



However, the conclusion given in the diagram is incorrect. So, what is the correct conclusion?
