In a double-slit experiment, if the wavelength of light is increased, what happens to the distance between the fringes?
Increases
Decreases
Remains the same
Becomes zero
The distance between the fringes increases with an increase in wavelength, as fringe separation is directly proportional to wavelength.

Q: In a double-slit experiment, if the wavelength of light is increased, what happens to the distance between the fringes?
Solution: The distance between the fringes increases with an increase in wavelength, as fringe separation is directly proportional to wavelength.
Steps: 5
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.
