Description

In the experiment P5.3.3.1, the Newton’s rings are investigated with monochromatic, transmitted light. At a known wavelength λ, the bending radius R is determined from the radii r_n of the interference rings. Here, the relationship for constructive interference is:

Thus, for the radii of the bright interference rings, we can say:
