In thin film interference, which of the following will cause a shift in the interference pattern? (2022)
Step 1: Understand that thin film interference occurs when light waves reflect off the top and bottom surfaces of a thin film.
Step 2: Recognize that the interference pattern is created by the combination of these reflected light waves.
Step 3: Identify that a shift in the interference pattern happens when there is a change in the path difference between the two waves.
Step 4: Realize that factors such as the thickness of the film, the angle of incidence, and the wavelength of light can all change the path difference.
Step 5: Conclude that any change in these factors will cause a shift in the interference pattern.
