Physics Optics Problem
An object 8 cm high is placed 20 cm in front of a converging lens of 10 cm focal length. A second converging lens of 20 cm focal length is plaed 30 cm behind the first lens. Find (a) the image distance for the first lens, (b) the object distance for the second lens, (c) the image distance for the second lens, and (d) the total magnification of the combination.

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...

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...

Problem 3: An object of height
2.8 cm is placed 26 cm in front of a diverging lens of focal length
16 cm. Behind the diverging lens, and 11 cm from it, there is a
converging lens of the same focal length.
a) Find the location of the final image, in centimeters beyond
the converging lens (such that a negative answer would indicate the
final image is on the same side of the converging lens as the
object).
b) What...
