Answer :
Answer:
d.The wavelength of light and the size of the aperture
Explanation:
The resolution power of an optical system is the smallest distance between two points that the device can distinguish clearly.
It has the following relationship:
[tex]r=\frac{\lambda}{2n}[/tex]
where:
r = minimum resolvable distance
n = numerical aperture
[tex]\lambda[/tex]= wavelength of the light used for viewing
From above mathematical equation it is clear that:
- Smaller the wavelength better the resolving power
- Larger the aperture better the resolution
(Note, that smaller the value of "r" the more finer details of the image visible through the device.)
