Title: Physlets Optics java applet: A simple object on the left of the lens and a lens Post by: lookang on September 02, 2008, 01:47:38 pm 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! |
