The limit of resolution of microscope, if the numerical aperture of microscope is `0.12`, and the wavelength of light used is 600 nm, is

A

`0.25xx10^(-7)m`

B

`2.5xx10^(-7)m`

C

`25xx10^(-7)m`

D

`250xx10^(-7)m`

Text Solution

Verified by Experts

The correct Answer is:
C
`25xx10^(-7)m`
`mu sin theta=0.12, lamda =6000Å, dimplies`
`d=(lamda)/(2 mu sin theta)`
`=(6xx10^(-7))/(2xx0.12)`
`=(6xx10^(-7))/(0.24)`
`d= 25xx10^(-7)m.`
