35. Light reflected from the front surface of the coating suffers a phase change of πrad while light reflected from the back surface does not change phase. If Lis the thickness of the coating, light reflected from the back surface travels a distance 2Lfarther than light reflected from the front surface. The difference in phase of the two waves is 2L(2π/λc) – π, where λcis the wavelength in the coating. If λis the wavelength in vacuum, then λ
