A microscope has an objective lens with an aperture of diameter 0.6 cm where a monochromatic light source of 580 nm is used to illuminate the object. It is determined that the minimum angle of resolution is 1.18 x 10 -4 rad. If the illuminating source were replaced by a violet source with wavelength of 420 nm, what would the minimum angle of resolution now become? (1 nm = 10 -9 m) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 1. 1.63 x 10 -4 rad 2. 1.18 x 10 -4 rad 3. 0.85 x 10 -4 rad 4. 0.58 x 10 -4 rad
