Wavelength of light used in an optical instrument are `lambda_(1)=400 Å ` and `lambda_(2)=5000 Å`, then ratio of their respective resolving power (corresponding to `lambda_(1)` and `lambda_(2))` is

A

`16:25`

B

`9:1`

C

`4:5`

D

`5:4`

Text Solution

Verified by Experts

The correct Answer is:
D
`R.P.=(1)/(lambda)implies((R.P.)_(1))/((R.P.)_(2))=(l_(2))/(l_(1))=(5)/(4)`
