What is the field of view of the 40x objective of the 4x objective has a field of view of 4.5mm?

o-na [289]

Answer:

field of view = 0.45 mm

Explanation:

given data

object lens = 4x

view microscope = 4.5 mm

to find out

field view at 40x

solution

we know microscope have objective lens like 4x or 10x or 100x that magnify 4 time or 10 time or 100 time respectively

so we can say that field of view will be decreasing by increasing number of magnify lens

so for clear resolution 40 x field of view will be

40 x field of view = 4x × 4.5 mm ..............1

field of view = $\frac{4*4.5}{40}$

field of view = 0.45 mm
