- a) At what angle is the first minimum for 550-nm light falling on a single slit of width 1.00 um? When i solve the question, there is no way i get the answer to be 33.4 deg. rather i get the sin-1 (0.55) = 0.58. IS the final answer wrong in the bartley and the test book or am i wrong?A lens with an index of refraction of 1.60 is to be coated with a material (n = 1.40) that will make the lens nonreflecting for yellow-orange light (λλ = 515 nm) normally incident on the lens.
