What is the effect on the interference pattern if the wavelength of light used in a double-slit experiment is increased? (2023)

Step 1: Understand what a double-slit experiment is. It involves shining light through two narrow slits to create an interference pattern on a screen.
Step 2: Know that the interference pattern consists of bright and dark fringes (lines) on the screen.
Step 3: Learn that the distance between these bright and dark fringes is called the fringe width.
Step 4: Recognize that the fringe width is affected by the wavelength of the light used in the experiment.
Step 5: Realize that if the wavelength of the light is increased, the fringe width also increases.
Step 6: Conclude that a larger wavelength means the bright and dark fringes will be spaced further apart on the screen.
