Explanation The portion of the soap in which the accompanying photograph is thinnest ar the top because it appears black at the top of the film. There is no phase change at the back surface of the film because it is reflected by rarer medium at the back surface while coming to front surface of the film, it undergoes a phase change of 180 ° because it is reflected by denser medium at the back surface
