A planoconvex lens of radius R and index of refraction n is placed curved side down on flat glass surface. This configuration is being used to measure the wavelength of light produced by a particular light source. If the radius of the dark rings produced by interference is r, what is the wavelength of the light? Assume the setup is in air
1. rn/mR 2. Rn/mr 3. mR/nr2 4. R2/mR
