Two converging lenses are separated by a distance of 20 cm. The first lens has a focal length of 5 cm and the second lens has an unknown focal length that you need to calculate. When an object is placed 8 cm in front of the first lens you measure a total magnification of M=-1.8 (That is, the magnification caused by the two lenses). Answer the following questions:
1. location of the image found by the first lens
2. magnification caused by the first lens
3. magnification caused by the second lens
4. location of the image formed by the second lens
5. focal length of the second lens

two thin lenses are separated by a distance x. The first lens has a focal length of 10cm, the second has a focal length of 5cm. An object is placed 15cm in front of the first lens which forms an image between the lenses. Find the separation between the lenses given that the final image is formed 10 cm behind the second lens. Please use pictures and show all steps.

Two converging lenses are placed 20 cm apart. An object is placed on the left of the first lens, at a distance of 30 cm. The first lens has a focal point of 10 cm and the second lens has a focal length of 20 cm. a) Using a ray diagram determine the type of image formed by the first lens. b) Calculate the position of the image formed by the first lens. c) Find the magnification of the image...

An object is located to the left of two lenses that are separated by a distance of 40 cm. The object is located at p1 = 45 cm in front of the first (diverging) lens with a -30 cm focal length, as sketched by an arrow in the figure below. The final image created by the two lenses is located 8.6 cm to the right of the second lens. (a) Clearly draw in the space below at least two of...
