Optometrists quantify the resolution of a patient’s vision using a concept called visual acuity, which is calculated as the inverse of the angular resolution of the eye measured in arc minutes (where 60 arc minutes 5 18) under standard illumination (i.e., in a normal room). The visual acuity of a typical person with normal eyesight is 1.0 in these units. 

(a) What is the visual acuity of a person who can just barely resolve two tiny objects separated by 1.0 mm at a distance of 35 cm? (These objects might be two small features on a printed page.) 

(b) Is this person’s visual acuity better or worse than the normal value mentioned above?
