A single-slit diffraction pattern is obtained on a screen placed at a distance of 10cm from the slit of width 5um . the wavelength of the monochromatic light used is 5.9 x 10^-7 m
how many dark fringes are found on the screen ?

我研究了很久还是研究不到要用哪个formula ==

single slit dark fringe formula

maximum order of dark fringe, theta = 90

就这样
