A microscope has an objective lens with a focal length of 19.5 mm and an eyepiece with a focal length of 6.2 mm. With the length of the barrel set an 33.0 cm, the diameter of a red blood cell’s image subtends an angle of 1.2 milli-radians with the eye. The final image distance is 29.0 cm from the eyepiece. (a) What is the length of the image of the of the cell produced by the eyepiece? (b) Using the...
