Paragraph Styles b) Measure the distances y, and y, from the middle of the central maximum (i.e. m = 0) to the center of the ist and 2nd bright fringes. Similarly, measure the distances y's and y1 for the first two dark fringes. Enter data into table below: c) For every value of y, calculate the wavelength 1 of the laser beam using the double-slit diffraction equations and find the average (in nm): m I'm (cm) a (nin) y in (cm ) a (mm ) Average / F d) Now adjust the frequency to the maximum on the sliding bar while keeping other configurations unchanged. Then repeat the steps in parts (b) and (c) to find the average wavelength 2 for this frequency: m I'm (cm) A (nm) Y m (cm) A (nm) ccessibility: Investigate FO 33 W
