 P: 118 Anyone got any suggestions? i was thinking it must have something to do with the phase differences on exit, but no idea how to relate this to the experiment. btw: here is a link http://physics.bu.edu/~duffy/semeste...ons_rings.html I know that the equation for the radius of the m'th Newton's bright ring is: $$x_m = \left[ {\left( {m + \frac{1}{2}} \right)\lambda R} \right]^{1/2}$$ where: R is the radius of curvature of the lens the light is passing through, m is 0,1,2,3... which is dependent upon the number of light spots, λ is the wavelength of the light passing through the glass.
