Title: Thin lens enhancements
Post by: John M. Clement on March 21, 2005, 01:17:51 pm
There is a common misconception that when half of a lens is covered that half of the image disappears.  This problem can be helped by two methods.  First, the simulation should be capable of drawing extra rays to show that there are multiple rays going through the lens.  This would be a useful option for the thin lens applet.

Second, a means for "blocking" part of the lens by an object should show the image becoming fainter, but still there.  This would be another useful enhancement.

You can drag any one of the black dot to change the following parameters:

 focus length(f), object position (p), height of object (h), slit width or slit position, position of lens ...
