Diffraction due to a single slit

Diffraction is the bending and spreading of waves as they pass through an aperture or around an obstacle. When a wave, such as light, passes through a narrow slit, the wave is diffracted and spreads out, producing a pattern of alternating bright and dark fringes on a screen placed behind the slit. This is known…

Tetrahedral and Octahedral

Tetrahedral and octahedral are two geometric shapes commonly found in chemistry and crystallography. Tetrahedral refers to a shape with four sides, each of which is a triangle. The tetrahedron is a regular solid with four identical equilateral triangles as its faces, and it is often used to describe the molecular geometry of compounds with four…
