In a location where the speed of sound is 332 m/s, a 2,000 Hz sound wave impinges on two slits 30 cm apart. (a) At what angle is the first-order maximum located? (b) If the sound wave is replaced by 3.35 cm microwaves, what slit separation gives the same angle for the first-order maximum? cm (c) If the slit separation is 1.00 um, what frequency of light gives the same first-order maximum angle? Hz Need Help? Submit Answer '-/1 Points] SERCP11 24.2.P.009. 0/100 Submissions Used ASK YOUR TEACHER Monochromatic light falls on a screen 1.65 m from two slits separated by 2.15 mm.
