To locate the position of an image formed by a lens using ray tracing, one needs to

have rays coming from multiple points of the object and find an intersect point.

have rays coming from one point of the object and find an intersect point.

have a ray going parallel to the axis.

have a ray pass through the edge of the lens without bending.

None of the above will give the location of the image.

When two lenses are used in combination, the first one forms an image that then serves as the object for the second lens. The magnification of the combination is the ratio of the height of the final image to the height of the object. A 1.50-cm-tall object is 58.0 cm to the left of a converging lens of focal length 40.0 cm. A second converging lens, this one having a focal length of 60.0 cm, is located 300 cm to...

A convex lens is lined up with a concave mirror so that they share the same optical axis. This axis is also defined to be the x-axis. A very small light bulb is placed near the lens so that light emanating from the bulb passes through the lens and forms an image that is located between the lens and the concave mirror. The location of the small bulb, however, is unknown. Listed below are the details about what is known...

An object 8 cm high is placed 12 cm to the left of a converging lens of focal length 8 cm. A second converging lens of focal length 6 cm is placed 36 cm to the right of the first lens. Both lenses have the same optical axis. Find the position, size and orientation of the image produced by the two lenses in combination. Confirm the validity of your result by drawing a ray-tracing diagram.

When two lenses are used in combination, the first one forms an image that then serves as the object for the second lens. The magnification of the combination is the ratio of the height of the final image to the height of the object.
