1. The problem statement, all variables and given/known data 1. A soap bubble is colored because of: a. dispersion b. diffraction c. thin film interference d. all of the above 2. Relevant equations 3. The attempt at a solution I dont understand the concepts very well...at first I though the answer was dispersion thinking it worked as a prism but the correct answer is supposed to be thin film interference. can someone explain to me the concept? (also I dont understand refraction very well either) thanks in advance!
