Ray Tracing (Converging Lens 2)

Ray tracing diagram for a converging lens, with the object inside the focal length. (yes, the light actually bends at both surfaces, not the middle of the lens...)

This video was made with a Samsung Document Camera (pretty much a digital video camera on a stick)

but how if there are two lenses?

@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

[pegru001]

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

@88Sabrine88 Thank you so much! I finished it and this question didn't come up, the diverging ones did :)
