An 8.1✕ binocular has 2.3 cm focal-length eyepieces. What is the focal length of the objective lenses?
the 8.1 is the magnification(m)=focal length of objective
lens/focal length of eyepiece lens
2.3 x 8.1= 18.63

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?
2. A microscope has a 1.1 cm diameter objective lens with a
focal length of 2.3 mm. The microscope is using light with a
wavelength of 550 nm.
Please help me break down and work through this practice
question so that I can better under the steps and work it out on my
own.

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 microscope has an objective lens of focal length 00 mm. The objective forms an image 18 cm from the lens. The focal length of the eyepiece is 70 cm. What is the distance between the lenses?
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...
What is the angular magnification of a telescope that has a 125-cm focal length objective and a 2.30-cm focal length eyepiece?
A Galilean telescope is made with a 40 cm focal length objective lens and a -10 cm focal length eyepiece. As is typical, the separation between the lenses is the sum of the focal lengths, i.e. 30 cm. Usually this telescope would be used to view far distant objects, but suppose the object viewed is only three focal lengths (120 cm) distant from the objective lens (a) On the figure above, sketch the principal rays that determine the size and location...
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?
The focal length of the objective of a telescope is 75.0 cm. While the eyepiece has a focal length of 6.00 cm, what is the magnifying power of this telescope? The answer is 12.5 I just need the work.
One lens has a focal length of +15.6 cm. A second lens of focal length +21.1 cm is placed in contact with the first lens. What is the equivalent focal length of the combination of lenses?
