To obtain any points for each problem, you must include all relevant formulas, justifications, calculations, substitutions, reasoning, and diagrams as needed. You must organize the steps of your work to be neat and clear. A thin layer of magnesium fluoride film (n = 1.38) is coated on a flint-glass lens (n = 1.61). Due to some manufacturing flaw, the reflection of light having a frequency of 5.17x1014 Hz has been augmented instead of being suppressed? (a) Draw a magnified sketch of two reflected rays showing path/phase difference at the applicable point/s, then calculate the minimum thickness of the layer that causes this defect? (b) What is the minimum thickness that corrects the defect? (8 points)
