Repeat Problem 40.1 for the case in which n 1 f > or n 1 > n

Question:

Repeat Problem 40.1 for the case in which n₁ f > or n₁ > n_f 2.

Problem 40.1

Figure 40-2 shows a thin film of a transparent material of thickness d and index n_f where n₂ > n_f > n₁. For what three smallest film thicknesses will reflected light rays-1 and -2 interfere totally Constructively and Destructively? Assume the monochromatic light has a wavelength in the film of 600 nm. nj n 12 d Fig. 40-2
