An engineer can increase the magnitude of the magnification of a compound microscope by
a. using a longer focal length objective.
b. using a shorter focal length eyepiece.
c. designing the microscope to have more distance between the objective and the eyepiece.
d. doing more than one of the above.
e. not doing any of the above.

Answer:

Option B

Explanation:

Magnification of Microscope is  

[tex]M = M_o \times M_e[/tex]

Mo= Magnification of objective lens and

Me= magnification of the eyepiece.  

Both magnifications( of objective and eyepiece) are inversely proportional to the focal length.  

Magnification,  

[tex] M\ \alpha\ \dfrac{1}{f}[/tex]

when the focal length is less magnification will be high and when the magnification is the low focal length of the microscope will be more.

Thus. Magnification will increase by decreasing the focal length.

The correct answer is Option B i.e. using shorter focal length
