Final answer:
Banding occurs when color migrates from a prior coat into a freshly applied one, a phenomenon attributed to thin-film interference. This optical effect manifests as colors appearing on the surface of a thin, transparent layer, creating a visual banding pattern in the coating. The correct answer is D. Banding.
Step-by-step explanation:
Banding, denoting the transfer of color from a prior coating to a newly applied one, manifests as narrower and brighter bands in the resulting pattern.
This phenomenon arises from thin-film interference, where colors emerge on the surface of a thin, transparent layer.
Capturing a lasting record of these occurrences can be achieved by documenting them on a material like paper or film.
This visual effect, characterized by distinct bands, provides insight into the interplay of colors in coatings, offering a means to analyze and understand the intricacies of thin-film interference and its impact on the final appearance of the coated surface.
Therefore, the correct answer is D. Banding.
