In a Young's double-slit experiment, a set of parallel slits with a separation of 0.100 millimeter is illuminated by light having a wavelength of 592 nanometer and the interference pattern observed on a screen 3.50 meter from the slits.
(a) Obtain the difference in path lengths from the two slits to the location of a fifth order bright fringe on the screen?
µm
(b) Find what is the difference in path lengths from the two slits to the location of the fifth dark fringe on the screen, away from the center of the pattern?
