Here
Power = 1/fe = 80.000
Therefore'
fe = 0.0125 m
Therefore
fo + fe = 1.6125
Therefore
fo = 1.6125 - 0.0125
= 1.6 m
Magnification = fo/fe
= 1.6/0.0125
= 128
(B)
Magnification is given as.
m= fo/fe
fo =m*fe
Here
fe +fo = d
So,
fe = d/(1+m)
Given m = 15
d = 42 cm
fe = 2.625 cm = 0.02624 m
Calculate the power of each lens.
Pe = 1/fe = 38.1 D
fo = 15 * 0.02624 = 0.3936 m
Po = 1/fo = 2.54 D

1. On one of the shelves in your physics lab is displayed an antique telescope. A sign underneath the instrument says that the telescope has a magnification of 23.0 and consists of two converging lenses, the objective and the eyepiece, fixed at either end of a tube 81.0cm long. Assuming that this telescope would allow an observer to view a lunar crater in focus with a completely relaxed eye, what is the focal length fe of the eyepiece? Note that...

After taking an astronomy class, you purchase an astronomical telescope that has a focal length for the objective and eyepiece respectively of 196 cm and 1.27 cm. After using the telescope several times, you decide to increase its angular magnification by replacing the eyepiece. After replacing the eyepiece, the length of the barrel must be adjusted in order to bring objects into focus. Determine the best angular magnification you can obtain, if the barrel can only be shortened by 0.54...
