What are the uses for converging lenses when the object is situated at these different distances:
(where F= Focal length)
Object is beyond 2F
Object is at 2F
Object beyond F and 2F
Object between F and the lens (one use is magnifying glasses, any others?)
please note: I know all the types of images formed at each distance just not examples of how the 'distances' or lenses are used in practise
Thanks for any help
