Find the slit separation for a double-slit experiment that will produce interference finges that are 0.0180 rad apart on a distant screen when the light has a wavelength λ= 590nm. Find the corresponding slit width for a diffraction experiment with the same apparatus and wavelength when the angular separation between first and second order diffraction minima is 0.0500rad.
