A microscope has an objective lens with a focal length of16.22mm and an eyepiece with a focal length of 9.60mm. Withthe length of the barrel set at 32.0cm the diameter of a red bloodcell's image subtends an angle of 1.43mrads with the eye. Ifthe final image distance is 29.0cm from the eyepiece, what is the actual diameter of the red blood cell?
