SUMMARY
The discussion centers on calculating the phase difference between two light waves traveling through different layers of plastic. Given the wavelengths and refractive indices, the calculations yield a phase difference of 5.71 radians after both waves emerge from the layers. The equations used include N1 = L1*n1/λ and N2 = L2*n2/λ, with the final phase difference expressed in radians rather than wavelengths. The confusion arises from interpreting the results, as the answer sheet presents the phase difference without units, which is deemed "bad form."
