Physlets Optics java applet: A simple object on the left of the lens and a lens

[lookang]

note that the object must be on the left of the lens.

the assumption is the light source is always shining from left to right!

Question!
can you explore and find out the focus length of the lens?













Hint:
an object placed exactly at the focus length of the lens will result in an image at infinity!
