Question:

The table below lists the angular positions of the bright fringes that result when monochromatic laser light shines through a diffraction grating, as a function of order m. The spacing between lines of the grating is d = 3.2?m. Determine a quantity that, when plotted against m, should give a straight line. Plot the data, determine a best-fit line, and use the result to find the wavelength of the light.
