Questions & Step-by-Step Solutions
In a double-slit experiment, if the wavelength of light is increased, what happens to the distance between the fringes?
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 wavelength of light is the distance between two peaks of the light wave.
Step 3: Realize that the distance between the fringes (fringe separation) is affected by the wavelength of the light used.
Step 4: Remember that if the wavelength increases, the distance between the fringes also increases.
Step 5: Conclude that the relationship between wavelength and fringe separation is direct; as one goes up, so does the other.
