Question

If the diameter of the field of view is 5.6 mm at 40x, what would the diameter be at 80x?

Answer 1

Answer:

2.8 mm

Explanation:

given,

diameter of field at 40x is equal to 5.6

diameter of field at 80 x = ?

Field of view is the circle you see when you look through the ocular lens of the microscope.

when you  use  80 X                    

then the diameter of the field of view becomes =

                                           = $\dfrac{5.6}{2}$

                                           = 2.8 mm

so, when we use 80 X the diameter becomes half of 40 X
