Reference no: EM13647062

Two laser beams are simultaneously illuminating a diffraction grating. One laser has a wavelength of 632.8 nm. and the other has a wavelength of 637.8 nm. How many slits per millimeter are required to resolve the first order diffraction bright spots. Assume the spots must be seperated by 5mm. to be distinct and use D = 1.0 meter.
