Angular resolution of telescope is of order of ...... for 10 cm objective diameter and 5000 Å wavelength of light.

A

`10^6` rad

B

`10^(-2)` rad

C

`10^(-4)` rad

D

`10^(-6)` rad

Text Solution

Verified by Experts

The correct Answer is:
A, D

`delta phi =1.22(lambda)/(D)`
`=1.22(5000xx10^(-10))/(10xx10^(-2))`
`=6.1xx10^(-6)`
`deltan=10^(-6)` rad
`lambda=5000` Å
`=5000xx10^(-10)m`
D=10 cm
`=10xx10^(-2)m`
