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, and 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).a) where is the image formed by the objective (distance to the objective)? b) what is the linear magnification of the objective? c) what is the angular magnification of the eyepiece? d) what is the length l of the tube of the microscope so that the final image viewed through the eyepiece is located at infinity?
