The normal human eye has maximum visual acuity with a pupil size of about 3 mm. For larger pupils, acuity decreases due to increasing aberrations; for smaller pupils, acuity decreases due to increasing effects of diffraction. Ifyour pupil diameter is 2.0 mm, as it would be in fairly bright light, what is the smallest diameter circle that you can barely see as a circle, rather than just a dot, if the circle is at your near point, 25 cm from your eye? Assume the light’s wavelength in air is 600 nm and the index of refraction inside theeye is 1.33.
A pinhole camera uses a tiny pinhole instead of alens. Show, using ray diagrams, how reasonably sharpimages can be formed using such a pinhole camera. Inparticular, consider two point objects 2.0 cm apart that are1.0 m from a 1.0-mm-diameter pinhole. Show that on apiece of film 7.0 cm behind the pinhole the two objectsproduce two separate circles that do not overlap.
