A technician directs monochromatic light toward a single slit in an opaque barrier. The light has a wavelength of 500 nm and the slit is 0.180 mm wide. The light that passes through the slit creates a diffraction pattern on a screen, which is 1.60 m from the slit. (a) How wide (in mm) is the central maximum (the central, bright fringe), as measured on the screen?
mm
(b) How wide (in mm) is either of the two first-order bright fringes, as measured on the screen?
mm
