10. A ray of light with a wavelength of 480 nm strikes a very thin soap film of thickness 2.00 nm, with air oneach side of the film. Which statement is true?a. There will be constructive interference because the path difference is effectively zero, andphase change occurs at only one surface.b. There will be destructive interference because the path difference is effectively zero, andphase change occurs at only one surface.c. There will be constructive interference because the path difference is effectively zero, andphase change occurs at either surface.d. There will be destructive interference because the path difference is effectively zero, andphase change does not occur at either surface.
