Question

presanted by Mapoob entr Physics sapling leaming The limit to the eye's acuity is actually related to diffraction by the pupil. What is the angle between two ust-esolvable points of light for a 6.75 mm diameter pupil, assuming the average wavelength of 539 nm? Number Take your result to be the practical limit for the eye. What is the greatest possible distance a car can be from you if you can resolve its two headlights, given they are 1.60 m apart? Number ITm What is the distance between two just-resolvable points held at an arm's length (0.900 m) from your eye? Number Im

Explanation / Answer

According to the question provided we need to find the following values.

Part a) sin theta = 1.22 lambda/D

theta = arcsin( 1.22*539.0E-9/6.75E-3)= 0.0055811 degrees a)

PART B) L = y/tan theta = 1.60/tan(0.0055811 degrees)= 16425.65 m =====B)

PART C) y = L tan theta = 0.900*tan(0.0055811 degrees)= 8.76677E-5 m ====C)
