If a microscope has a resolving power of 0.2 microns?

Question

and the naked eye of a human has a 0.1mm resolving power. How much does it increase between the human eye and the microscope?

Answer 1

0.1mm = 1X10^(-4) m

0.2 microns = 2X10^(-7) m

Increase factor

= 1X10^(-4)/2X10^(-7)

= 1X10^7/2X10^4

= 1X10^3/2

=1000/2

=500 = Ans

An optical microscope used forobserving bacteria often uses a magnification of 1000. Any more would only magnify the blur.
