@streetsesh80 If there are two lenses, ignore one of them, and draw the diagram for the other lens. Then, use the image from this first lens drawing as the object for the second lens drawing. And...that's it.
Why didn't you do the bottom one? i''m confused with it. when i draw the parallel and the middle ray, they meet. but i dont know how to draw the last ray
how to distinguish between real and virtual image? i still dont get it... when virtual , is it cannot be seen or else? your explanation will be such a great help...thanks...
@RuDofCAraVAn: In real life, both types of images are visible to the human eye. The difference is that a real image can be projected onto a screen, and a virtual image cannot be. For example, if you take a converging lens, place it in front of a window, place a white piece of paper near the lens on the side opposite the window, you will see an upside down image of the window on the paper. This doesn't work with a diverging lens.
@RuDofCAraVAn: On the raytracing diagram: if the image is on the same side of the lens as the object, that image is virtual. If the image ends up on the opposite side of the lens, that image is real.
but how if there are two lenses?

@xsfxing The bottom one works out basically the same as the top one; see Ray Tracing (Converging Lens). hope this helps
