corresponds to an angular resolution of 6 arcseconds. To measure the loss of most intense at a wavelength of 700 nanometers (1 nanometer = 10. -9 meters).
The angular resolving power (or resolution) of a telescope is the smallest angle between close objects that can be seen clearly to be separate. Read More
Angular resolution or spatial resolution describes the ability of any image-forming device such as an optical or radio telescope, a microscope, a camera, or an eye, to distinguish small details of an object, thereby making it a major determinant of image resolution.
The basic accuracies of the human eye are: Quick autofocus from distances of 25 cm (young people) to 50 cm (most people 50 years and older) to infinity. Angular resolution: about 1 arcminute, approximately 0.02° or 0.0003 radians, which corresponds to 0.3 m at a 1 km distance.
It is a product of angular resolution and focal length: ?F=??/D. Specifically, this is . Diffraction image of a point source on the surface of most extended objects
