A narrow single slit (in air) in an opaque screen is illuminated by infrared from a He-Ne laser at 1,152.2 nm, and it is found that the center of the tenth dark band in the Fraunhofer pattern lies at an angle of 6.4° off the central axis. Determine the width of the slit. At what angle will the tenth minimum appear if the entire arrangement is immersed in water (n=1.33) rather than air (n = 1.00029)?

Sound waves with frequency 4000 Hz and speed 350 m/s diffract through the rectangular opening of a speaker cabinet and into a large auditorium of length 100 m. The opening, which has a horizontal width of 31.0 cm, faces a wall 100 m away. Along that wall, how far from the central axis will a listener be at the first diffraction minimum and thus have difficulty hearing the sound?
