Question

A fringe pattern, such as that in Figure $20,$ found using an interference microscope objective, is observed to have a regular spacing of $1 \mathrm{mm} .$ At a certain point in the pattern, the fringes are observed to shift laterally by $3.4 \mathrm{mm}$. If the illumination is green light of $546.1 \mathrm{nm}$, what is the dimension of the "step" in the film that caused the shift?
