Question

In single-slit diffraction, what happens to the dark fringes if the slit gets wider?

A) Nothing; the spacing between the fringes does not depend on the width of the slit.

B) They get further apart.

C) Nothing; there are no dark fringes when there is only one slit.

D) They get closer together.

Answer 1

Answer #1

D) They get closer together, because

Increasing the size of the opening reduces the spread in the pattern.

option D is correct

Answer 2
