Question

Please Help! can someone walk me through how O actually come up with slope? i inderstand that dym is the y values and ml is the x, but I cant figure out what those values are.

I used a He-Ne Laser, wavelength = 632.8 nm, and shined through two slits whose separation distance is d = 0.250 mm. The light was shined upon a sheet of paper taped to the wall and was 10.0 ft 4.00 inches away from the double slit. I circled the bright spots (constructive interference) and identified the central maximum (m = 0). I saved the lab data as a pdf file with a 1:1 ratio. I was able to identify seven bright fringes on either side of the central maximum. Let ym measure the distance from the central maximum to the mth constructive interference. For positive m, let ym be positive, and for negative order (negative m), let ym be negative. m = -7 to 7 they are 1 cm apart Ym, m d m=0 L m = mi uym 1150 Take the derived equation and solve for the wavelength. 13 L ml run Create a scatter plot, using the indicated x and y values and determine the slop of the line that best fits your scatter plot. I want you to make the units for the slope to be in nanometers. Determine the percent error between the value you obtain from the slope to the theoretical value of 632.8 nm.
