This is similar to the diagram above except the wavelength is different. This time XOY is not a number of whole wavelengths and so ray 1 and 2 arrive at y out of step. The troughs of ray 1 line up with the humps of ray 2 and the two rays cancel each other out. The overall effect is that no blue light will be reflected for this thickness of bubble.
