A geneticist looks through a microscope to determine the phenotype of a fruit fly. The microscope is set to an overall magnifica
Ugo [173]

Answer:

f_{e}  = 1.9 cm

Explanation:

The magnification of a microscope is the product of the magnification of the eyepiece by the magnifier with the objective

    M = M₀ m_{e}

Where M₀ is the magnification of the objective and  m_{e} is the magnification of the eyepiece.

The eyepiece is focused to the near vision point (d = 25 cm)

       m_{e} = 25 /  f_{e}

The objective is focused on the distances of the tube (L)

     M₀ = -L / f₀

Substituting

     M = - L/f₀    25/f_{e}  

1) Let's look for the focal length of the eyepiece (faith)

     f_{e}  = - L 25 / f₀ M

     M = 400X = -400

     f_{e}  = - 12 25 /0.40 (-400)

     f_{e}  = 1.875 cm

Let's approximate two significant figures

    f_{e}  = 1.9 cm
