Part A (Figure 1) shows a light wave incident on and passing through a thin soap film. Reflections from the front and back surfaces of the film create smaller waves (not shown in the figure) that travel to the left of the film, where they interfere. What is the thickness of the film in terms of the light wavelength inside it? Express your answer as a multiple of wavelength to two significant figures. d = Submit Request Answer Part B Figure 1 of 1 Do the reflections from the film surfaces have a phase shift or not? Reflections from the both surfaces of the film do not have a phase shift. Soap film Reflection from the right surface of the film has a phase shift while reflection film does not have a phase shift. Reflection from the left surface of the film has a phase shift while reflection fm film does not have a phase shift. Incident wave Reflections from the both surfaces of the film have a phase shift.
