Question
Your friend is entertaining his cat by shining two laser pointers with wavelength A = 630 nm on a wall located L = 12m away from the cat. When the cat first notices the laser spots, her pupils are roughly the shape of narrow vertical slits with width w = 2.0 mm. (a) Make a sketch of this scenario, including the two spots, the cat's eye, and the diffraction patterns that are created. (b) What is the minimum separation distance the two spots can have while the cat is still able to resolve them as two separate spots? (c) The cat's pupils dilate so that they become roughly circular with a diameter of D = 6.0 mm. Now what is the minimum separation distance the two spots can have?
