If the wavelength of light used is 6000 ...

If the wavelength of light used is 6000 Å. The angular resolution of telescope of objective lens having diameter 10 cm is ...... Rad

A

`6.10xx10^(-6)`

B

`7.32xx10^(-6)`

C

`6.55xx10^(-6)`

D

`7.52xx10^(-6)`

Text Solution

Verified by Experts

The correct Answer is:
B
Angular resolving power of telescope
`alpha_(min)=(1.22 lambda)/(D)`
`=(1.22xx10^(-5)xx6)/(10)`
`=7.32xx10^(-6)`
