hi guys i have done many past papers. so many times i have seen question about bright fringes,dark fringes maximas or minimas
Can anyone explain me fully that how to find maximas minimas or greatest no of maximas in diffraction grating and one thing more no of lines per mm is D or 1/N ??? in this case wavelength and no of lines per mm is given
i think this type of question also came in oct /nov 2012 variant 12 que 30 plzz try it
