a microscope has a converging lens (the eyepiece) with a focal length of f1=1.73cm 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 f2=29.04 cm. when you place a small flea you want to examine at a distance of s1=3.36 cm from the objective . find the overall length of the microscope needed to view the sample (the flea) in focus with a completely relaxed eye? hint- a normal relaxed eye will expect to find an image at infinity . the length l of the microscope here is the distance between the eyepiece and the objective lens as shown in the fingure.
express your answer in cm and to two decimal places.

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. Part A 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...

A compound microscope has the objective and eyepiece mounted in a tube that is 18.8 cm long. The focal length of the eyepiece is 2.55 cm , and the near-point distance of the person using the microscope is 24.0 cm . If the person can view the image produced by the microscope with a completely relaxed eye, and the magnification is -4516, what is the distance between the objective lens and the object to be examined?
