Q: In thin film interference, which of the following will not affect the interference pattern? (2022)
Solution: While thickness, wavelength, and angle of incidence affect the interference pattern, the color of the light source does not directly affect the pattern itself.
Steps: 4
Step 1: Understand what thin film interference is. It occurs when light waves reflect off the top and bottom surfaces of a thin film, like soap bubbles.
Step 2: Identify the factors that can affect the interference pattern. These include the thickness of the film, the wavelength of the light, and the angle at which the light hits the film.
Step 3: Recognize that the color of the light source is related to its wavelength, but it does not change the interference pattern itself directly.
Step 4: Conclude that while thickness, wavelength, and angle of incidence are important, the color of the light source does not affect the interference pattern.
