I'm confused about the single slit diffraction pattern. Why are light and dark patterns? Where is the constructive and destructive interference occurring if there is just one wave?

Single slit diffraction is a phenomenon that occurs when a wave passes through a narrow slit. This causes the wave to spread out and create a diffraction pattern on the other side of the slit.
Single slit diffraction occurs when a wave passes through a single narrow slit, while double slit diffraction occurs when a wave passes through two closely spaced slits. Single slit diffraction creates a central maximum and a series of smaller maxima and minima, while double slit diffraction creates multiple interference patterns.
The width of the slit, the wavelength of the wave, and the distance between the slit and the screen all affect the diffraction pattern in single slit diffraction. A wider slit, longer wavelength, and shorter distance will result in a wider central maximum and a smaller diffraction pattern.
Single slit diffraction occurs due to the wave nature of light. When a wave passes through a narrow slit, the wavefronts diffract or bend around the edges of the slit, creating a diffraction pattern on the other side.
Single slit diffraction is used in various applications such as studying the wave nature of light, creating diffraction gratings for spectroscopy, and improving the resolution of optical instruments. It is also used in the production of holograms and in the design of acoustic diffusers for soundproofing.
