Consider two converging lenses2g,,h 9gnhh *rl ,nghy separated by some distance. An object is placed s,gh*l,hg9 ryn,hh2 n g- yu 1i ,2zv33d tlz8xmdhoi2jo that the image from the first lens lies exactly at the focal point of the second lens. Will this combination produce an image?

参考答案: When
an object is placed so that its image from one converging lens is placed at the
focal point of a
second converging
lens, the final image is formed at infinity by the second lens. A real image is similar to a real object and
when this image is placed at the focal point of another lens, the rays will
head to the second lens in such a way as to be sent out on the other side of
the lens in a direction parallel to the optical axis, which forms an image at
infinity.
