If the wavelength of light used in a double-slit experiment is increased, what happens to the fringe separation? (2022)
Step 1: Understand what a double-slit experiment is. It involves shining light through two narrow slits to create a pattern of light and dark stripes called fringes.
Step 2: Know that the distance between these fringes is called fringe separation.
Step 3: Learn about wavelength. Wavelength is the distance between two peaks of a wave of light.
Step 4: Recognize that fringe separation is affected by the wavelength of the light used.
Step 5: Remember the relationship: if the wavelength increases, the fringe separation also increases.
Step 6: Conclude that a longer wavelength means the fringes will be spaced further apart.
