In a thin film interference, if the film is viewed in white light, which color will appear at the center of the pattern?

In a thin film interference, if the film is viewed in white light, which color will appear at the center of the pattern?

Step 1: Understand that thin film interference occurs when light reflects off the top and bottom surfaces of a thin film.
Step 2: Know that different colors of light have different wavelengths. Red light has the longest wavelength among visible colors.
Step 3: When white light passes through the thin film, it creates an interference pattern with various colors.
Step 4: The center of the interference pattern typically shows the color with the longest wavelength, which is red.
Step 5: Therefore, in a thin film viewed in white light, red light will appear at the center of the pattern.
