MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The distance between the eyepiece and the objective lens in a certain compound microscope is 20.1 cm. The focal length of the objective is 0.470 cm, and that of the eyepiece is 1.90 cm. Find the overall magnification of the microscope. (The near point of the eye is 25 cm. Assume that the object is placed at the focal point of the objective lens, and one places the eyepiece at the near point of the eye. ) Need Help? Read It15. [-/3 Points] DETAILS SERCP11 25.5.P.031. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The two lenses of a compound microscope are separated by a distance of 19.0 cm. If the objective lens produces a lateral magnification of 13.0x and the overall magnification is 123x, determine the angular magnification of the eyepiece, the focal length of the eyepiece in cm, and the focal length of the objective lens in cm.
