Light of wavelength 520 nm passes through a double slit, yielding a diffraction pattern whose graph of intensity versus angular position is shown in the figure. Calculate (a) the slit width and (b) the slit separation. If Im = 7.8 mW/cm², what are the intensities of the (c) m and (d) m² interference fringes?
(a) Number: 5966.330888
Units: nm
(b) Number: 23865.32355
Units: nm
(c) Number: 0.6319209
Units: mW/cm²
(d) Number: [missing value]
Units: mW/cm²
