A thin soap film with an index of refraction of n = 1.33 is suspended in air (n = 1.00) and illuminated at near-normal incidence by light with a wavelength of \lambda in air. At a particular point on the film, the thickness t satisfies the condition 2nt = \lambda. Which of the following correctly describes the type of interference that occurs at this point for light of wavelength \lambda in the reflected beam and in the transmitted beam?
