$1$ Multiple Choice $2$ points

Light from a helium$-$neon laser is shined on a slit of width $0\mathrm{.}02$ mm $.$ Describe qualitatively the pattern of light seen on a screen $1\mathrm{.}0$ meter away. Assume that the slit is vertical.

The pattern on the wall has a broad central spot, with a series of dimmer spots on either side.

The pattern on the wall looks like a fuzzy slit, but turned on its side $($so it is much broader than it is tall$).$

The pattern on the wall has the same shape as the slit, but fuzzier as well as bigger.

The pattern looks exactly like the original slit, just bigger.
