Interference in Soap Films The sketch (Figure 1) shows a thin film of soapy water of uniform thickness t and index of refraction n = 1.33 suspended in air. Consider rays 1 and 2 emerging from the film: Ray 1 represents the reflected wave at the air- film interface and ray 2 represents the wave that reflects off the lower surface of the film. Figure air film air 1 of 1 Part A Which of the following statements correctly describes rays 1 and 2 and their path difference? Check all that apply. ► View Available Hint(s) Ray 1 undergoes a half-cycle phase shift. Ray 2 does not undergo any phase shift. Both rays 1 and 2 undergo a half-cycle phase shift. O Ray 2 undergoes a half-cycle phase shift. Ray 1 does not undergo any phase shift. The path difference between rays 1 and 2 is about t. There is no path difference between the two rays. The path difference between rays 1 and 2 is about 2t.
