In a thin film of oil on water, which color of light is most likely to be reflected? (2022)
Step 1: Understand that a thin film of oil on water can create colorful patterns due to light interference.
Step 2: Know that different colors of light have different wavelengths. Blue light has a shorter wavelength compared to other colors.
Step 3: Recognize that when light hits the thin film, some light reflects off the top surface and some goes through and reflects off the bottom surface.
Step 4: Realize that the thickness of the oil film affects which colors are reflected more strongly.
Step 5: Conclude that shorter wavelengths, like blue light, are more likely to be reflected prominently in thin films.
