how to calculate intensity for a given path differnce ( n lemda ) in interfence phenomenon if the maximum intensity (I) is given.
a beam of light of wavelength 6000A from a distant source falls on single slit of 1mm wide and resulting diffraction pattern is observed on screen 2m away. the dist of 1st bright fringe on either side of central bright fringe is
1) 1.2mm 2) 0.6mm 3) 2.4mm 4) 1.2mm
