What happens to the interference pattern if the wavelength of light is increased?

Step 1: Understand what an interference pattern is. It is a pattern created when light waves overlap and combine.
Step 2: Know that the wavelength of light is the distance between two peaks of the light wave.
Step 3: Realize that fringe width is the distance between the bright or dark spots in the interference pattern.
Step 4: Learn that fringe width is directly related to the wavelength of the light used.
Step 5: If you increase the wavelength of the light, the distance between the bright and dark spots (fringe width) also increases.
Step 6: Therefore, when the wavelength of light is increased, the interference pattern spreads out more.
