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!




Physlets®, i.e., the Java applets themselves, are a registered trademark of Wolfgang Christian.

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!
