Question

A double-slit experiment yields an interference pattern due to the path length difference from light traveling through one slit versus the other. Why does a single slit show a diffraction pattern?

A double-slit experiment yields an interference pattern due to the path length difference from light traveling through one slit versus the other. Why does a single slit show a diffraction pattern?

The single slit must have something in the middle of it, causing it to act like a double slit. There is a path length difference from waves originating at different parts of the slit. The wavelength of the light is shorter than the slit. The light passing through the slit interferes with light that does not pass through.

Explanation / Answer

Correct ans is option B.

light bends around the obstacles like the waves and this bend cause the diffrection pattern.

single slit shows a diffrection pattern because of the path length difference from waves originating at different parts of the slit..
