The angular resolution of a 10 cm diameter telescope at a wavelength of 5000 Å is of the order of .....

Options

A. `10^(6)` rad
B. `10^(-6)` rad
C. `10^(-4)` rad
D. `10^(-2)` rad

Answer

B

Explanation

Angular resolution of telescope,
`=(1.22 lambda)/(d)`
`=(1.22xx5xx10^(-7))/(10^(-1))`
`=6.1xx10^(-6)`
`=10^(-6)` rad
