We're doing a classic experiment in lhysics lab on measuring the
wavelength of a laser using a GEPE difraction grating with 4 slits
per mm, where we measure the X values between N=0, and N=1,2,3,...
in order to graph the values and calculate a wavelength.
Given that my group set the grating to 304.8cm away from the
wall, 10ft, we only had a tape measure... and measured the
following x values for each value of N, could someone derive the...
