The microscope available in your biology lab has a converging lens (the eyepiece) with a focal length of 2.50 cm mounted on one end of a tube of adjustable length. At the other end is another converging lens (the objective) that has a focal length of 1.00 cm. When you place the sample to be examined at a distance of 1.30 cm from the objective, at what length I will you need to adjust the tube of the microscope in order to view the sample in focus with a completely relaxed eye? Note that to view the sample with a completely relaxed eye, the eyepiece must form its image at infinity. The length I here is the distance between the eyepiece and objective lens. Express your answer in centimeters.

Question
In a two-lens system, the image produced by one lens acts as the object for the next lens. This simple principle finds applications in many optical instruments, including some of common use such as the microscope and the telescope.
