Which of the following experiments will produce constructive interference at the point of view of the observer (eye). The index of refraction of the soap film is 1.25 and there is air above the soap film. In experiments I) (t=300 nm) and III) (t=250 nm) there is air below the soap film, but in experiment II) (t=100 nm) there is a glass with index of refraction equal to 1.5. Assume that in all cases the light is nearly normal to the surface and that the light has 400 nm wavelength in the soap film.
A. None
B. Experiment I only
C. Experiment II only
D. Experiment I and III only
Assume that the light intensity is the same in all cases. Which of the following is true?
