In a compound microscope, the objective has a focal length of 0.48 cm, while the eyepiece has a focal length of 1.9 cm. The separation between the objective and the eyepiece is L = 10.0 cm. Another microscope that has the same angular magnification can be constructed by interchanging the two lenses, provided that the distance between the lenses is adjusted to a value L'. Find L'.

A compound microscope has an objective lens with a focal length of 0.40 cm and an ocular (eyepiece) with a focal length of 4.25 cm. The separation between the lenses is 20 cm. (a) Find the total magnification. (b) What focal length of the objective should be used to double the total magnification, if the focal length of the eyepiece and its separation from the objective remain the same?
In a compound microscope, the focal length of the objective is 3.71 cm and that of the eyepiece is 6.60 cm. The distance between the lenses is 17.6 cm. (a) What is the angular magnification of the microscope if the person using it has a near point of 32.1 cm? (b) If, as normal, the first image lies just inside the focal point of the eyepiece, as in the drawing, how far is the object from the objective? (c) What...
4 of 5 The focal length of the eyepiece of a certain microscope is 20.0 mm. The focal length of the objective is 10.0 mm. The distance between objective and eyepiece is 25.0 cm. The final image formed by the eyepiece is at infinity. Treat all lenses as thin. What is the distance from the objective to the object being viewed? What is the magnitude of the linear magnification produced by the objective? What is the overall angular magnification of...

A compound microscope has objective and eyepiece lenses of focal lengths 0.80 cm and 4.0 cm, respectively. If the microscope length is 15 cm, what is the approximate magnification of the microscope?
A compound microscope has an objective of focal length 0.300 cm and an eyepiece of focal length 2.50 cm. If an object is 3.40 mm from the objective, what is the magnification? (Hint: Use the lens equation for the objective.)
The distance between the lenses in a compound microscope is 18 cm. The focal length of the objective is 1.5 cm. If the microscope is to provide an angular magnification of -88 when used by a person with a normal near point (25 cm from the eye), what must be the focal length of the eyepiece?
The distance between the lenses in a compound microscope is 18 cm. The focal length of the objective is 1.5 cm. If the microscope is to provide an angular magnification of -64 when used by a person with a normal near point (25 cm from the eye), what must be the focal length of the eyepiece?
