In this equation, the computed angle is in radians. Remember that there are 206,265 arcseconds in one radian.
The minimum angular separation of two sources that can be distinguished by a telescope depends on the wavelength of the light being observed and the diameter of the telescope. This angle is called the DIFFRACTION LIMIT.
