The ratio of resolving power of telescope, when lights of wavelength 4400Å and 5500Å are used, is ____

A

`16:25`

B

`4:5`

C

`9:1`

D

`5:4`

Text Solution

Verified by Experts

The correct Answer is:
D
Resolving `prop 1/lambda`
`(theta_1)/(theta_2) = (lambda_2)/(lambda_1) = (5500)/(4400) = 5/4`
