Question

Using violet light, what happens in the simulation if you move the two slits closer to the screen (i.e. decrease L by moving the barrier further to the right)?

a. The distance between bright fringes decreases.
b. The distance from the central maximum to the first fringe increases. C
c More fringes appear on the screen.
d. Less fringes appear on the screen.
e. The distance between bright fringes increases.
f. The distance from the central maximum to the first fringe decreases

Answer 1

When the two slits in a double-slit interference experiment are moved closer to the screen, the distance between the bright fringes increases.

Step-by-step explanation:

When the two slits in a double-slit interference experiment are moved closer to the screen, the distance between the bright fringes increases. This is because the interference pattern is determined by the wavelength and slit separation. As the slits are moved closer, the wavelength remains the same, but the slit separation decreases, resulting in a larger distance between the bright fringes. Therefore, the correct answer is e. The distance between bright fringes increases.
