Question

The resolving power of human eye(in minute)

Answer 1

20/20 in 60arc second

Answer 2

Resolving power is the ability of the eye, or an optical instrument, to differentiate between two points or lines. It is typically expressed as an angle of separation radiating outward from the eye or instrument. When resolving power is expressed as an angle, simple geometry permits us to calculate the relationships between viewing distance and line or point separations. anyone's real eye would be capable of resolving two lines 1 mm apart from a distance 34 feet. The actual resolving power of the human eye with 20/20 vision is typically considered to be about one arc minute or 60 arc seconds, which is about one-third of the theoretical resolution we just calculated based solely on the diameter of the pupil. In fact, it is a little more complicated.
