The microscope has a converging lens (the eyepiece) with a focal length of 2.50 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 . When you place the sample to be examined at a distance of 1.30 from the objective, at what length will you need to adjust the tube of the microscope in order to view the sample in focus with a completely relaxed eye?
