Chapter 36 379 *P36.78 The first lens has focal length described by 1 1 1 1 1 1 1 1 1 1 11 12 1 1 f n R R n R n R = F H G I K J = F H G I K J = − b g b g . For the second lens 1 1 1 1 1 1 1 2 1 2 2 21 22 2 2 f n R R n R R n R = F H G I K J = + F H G I K J = + b g b g b g . Let an object be placed at any distance p 1 large compared to the thickness of the doublet. The first lens forms an image according to 1 1 1 1 1 1 p q f + = 1 1 1 1 1 1 q n R p = + . This virtual q 1 0 < b g image is a real object for the second lens at distance p q 2 1 = − . For the second lens 1 1 1 2 2 2 p q f + = 1 2 2 1 2 2 1 2 2 1 1 2 1 1 2 2 2 2 1 2 1 1 2 1 1 q n R p n R q n R n R p n n R p = = + = + + = . Then 1 1 2 1 1 2 2 1 p q n n R + = so the doublet behaves like a single lens with 1 2 1 2 1 f n n R = .

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
