In a thin film of oil on water, what color will be seen if the film thickness is such that it causes constructive interference for blue light?

In a thin film of oil on water, what color will be seen if the film thickness is such that it causes constructive interference for blue light?

Step 1: Understand what a thin film is. A thin film is a layer of liquid (like oil) that is very thin and sits on top of another liquid (like water).
Step 2: Learn about constructive interference. This happens when light waves combine in a way that makes certain colors brighter.
Step 3: Identify the color of light. In this case, we are focusing on blue light.
Step 4: Know that if the film thickness is just right, it will enhance the blue light through constructive interference.
Step 5: Conclude that if the film thickness causes constructive interference for blue light, then blue will be the color seen.
