The ratio of resolving power of an optical microscope for two wavelength `lambda_(1)=4000Å` and `lambda_(2)=6000Å` is:

A

`8 : 27`

B

`9 : 4`

C

`3 : 2`

D

`16 : 81`

Text Solution

Verified by Experts

The correct Answer is:
C
As resolving power of an optical microscope varies inversely as wavelength of light used, therefore
`(RP_(1))/(RP_(2)) = (lambda_(2))/(lambda_(1)) = (6000)/(4000) = 3 : 2`
