Question: In a double-slit experiment, if the distance to the screen is increased, what happens to the fringe separation?

Options:

Correct Answer: Fringe separation increases

Solution:

Fringe separation is directly proportional to the distance from the slits to the screen (D), so increasing D increases the fringe separation.

In a double-slit experiment, if the distance to the screen is increased, what happens to the fringe separation?

In a double-slit experiment, if the distance to the screen is increased, what happens to the fringe separation?

Step 1: Understand what fringe separation means. It is the distance between the bright or dark lines (fringes) on the screen in a double-slit experiment.
Step 2: Know that the distance from the slits to the screen is called D.
Step 3: Remember that fringe separation is directly related to this distance D.
Step 4: If you increase the distance D (make it larger), the fringe separation also increases.
Step 5: Therefore, when you increase the distance to the screen, the fringes will be spaced further apart.

Double-slit experiment – A fundamental experiment in quantum mechanics demonstrating the wave-particle duality of light and matter, where light creates an interference pattern when passing through two closely spaced slits.
Fringe separation – The distance between adjacent bright or dark fringes in the interference pattern, which is influenced by the distance from the slits to the screen.
Proportionality – The relationship where one quantity increases or decreases in direct relation to another quantity, in this case, fringe separation being directly proportional to the distance from the slits to the screen.
