In a thin film of oil on water, which color will appear at the topmost layer when viewed from above?

Step 1: Understand that a thin film of oil on water can create different colors due to light interference.
Step 2: Know that light is made up of different colors, each with its own wavelength (like red, blue, green).
Step 3: Realize that when light hits the oil film, some light reflects off the top surface and some goes through to the water and reflects back.
Step 4: Understand that the thickness of the oil film affects how these reflected light waves interact with each other.
Step 5: Remember that red light has a longer wavelength and is less affected by the interference compared to other colors.
Step 6: Conclude that when you look at the topmost layer of the oil film, red light is usually the color that appears.
