Solve the following problem given below:
Problem: An interference filter is constructed from two semi reflecting mirrors (r2 = 0.5) separated by a film of plastic which has an index of refraction of 1.35. The pass band of the filter is to be centered at 550 nm for normal incidence.
Part A- Determine the Chromatic resolving power for these first two orders (normal incidence).
Rework your solution from the beginning and check each step carefully.
