Question

The limit of resolution of microscope, if the numerical apertura of microscope is 0.12, and the wavelength of light used is 600 nm, is (A) 0.3 μ m (B) 1.2 μ m (C) 2.5 μ m (D) 3 μ m

For a microscope, the limit of resolution is given by,

< b r / > X = \frac{λ}{2 A} < b r / >

where

λ

is the wavelength of light used, and

A

is the numerical aperture. Hence, substituting the values,

X = \frac{600}{2 \times 0.12}

,
which gives,

X = 2.5 μ m

$3 μ m$

For a microscope, the limit of resolution is given by,
$< b r / > X = \frac{λ}{2 A} < b r / >$
where $λ$ is the wavelength of light used, and $A$ is the numerical aperture. Hence, substituting the values, $X = \frac{600}{2 \times 0.12}$ ,
which gives, $X = 2.5 μ m$
