the equation we were given to use was r = d(squared) / 4.N.wavelength the wavelength was 0.000588m the value for d(squared) was 1.955 My actual value was 831mm (sorry wrote the wrong figure down before) although i think there may be a problem with the equation we were given to use...

Hi there In an experiment I have calculated the radius of curvature for a +0.25D lens using Newtons rings and have obtained a value for 892mm, but the radius of curvature for a +0.25D lens is just over 2 metres. why is the value i got so much lower? do i have to double the value i got for the...
