In a thin film of oil on water, which color will appear at the center of the pattern if the film thickness is such that it causes constructive interference for red light? (2022)
Step 1: Understand that a thin film of oil on water can create colorful patterns due to light interference.
Step 2: Know that constructive interference happens when certain wavelengths of light reinforce each other.
Step 3: Identify that red light is the wavelength that is causing constructive interference in this scenario.
Step 4: Conclude that the color that will appear at the center of the pattern is red, since it is the wavelength that is being reinforced.
