Ripple Tank: Single and Double Slit Diffraction and Interference
With a narrow single slit opening we see a plane wave emerge as a spherical wave on the other side of the barrier. This can be explained by the Huygens-Fresnel principle which states that each point in the slit forms its own spherical wavefront source. With a wider slit, more point sources arise, causing interference patterns due to the larger angles involved with a broader spatial distribution of these sources.
