9. The condition for a minimum of intensity in a single-slit diffraction pattern is asin θ= mλ, where ais the slit width, λis the wavelength, and mis an integer. To find the angular position of the first minimum to one side of the central maximum, we set m= 1: 111934589 10100 10589 10=FHGIKJ=××FHGIKJ=×−−−−−sin...λammradIf Dis the distance from the slit to the screen, the distance on the screen from the center of the pattern to the minimum is yD43300589 101767 10==×=
