Multiple Choice Questions
If you add a third slit to two slits, with the same slit separation, and shine the same laser beam on the three slits, how will the three-slit pattern compare to the double-slit pattern? a. It will be the same, only brighter.
b. It will be the same, only the spots will be farther apart.
c. The centers of its bright fringes will be the same distance from each other, but their width will be narrower, additional spots will appear between them.
d. The centers of its bright fringes will be the same distance from each other, and their width will be narrower; no additional spots will appear.
