Bookmark or Share- Fine Structure Constant - Science Notes and ProjectsThe fine structure constant, symbolized as α (alpha), is a fundamental physical constant that indicates the strength of the interaction between charged particles. It plays a crucial role in the realms of quantum mechanics and electromagnetism. Other names for the constant are the coupling constant or the Sommerfeld constant in honor of Arnold ...
- Standard model of particle physics tested by the fine-structure constantEvery physicist knows the approximate value (1/137) of a fundamental constant called the fine-structure constant, α. This constant describes the strength of the electromagnetic force between ...
- Fine structure - WikipediaIn atomic physics, the fine structure describes the splitting of the spectral lines of atoms due to electron spin and relativistic corrections to the non-relativistic Schrödinger equation. It was first measured precisely for the hydrogen atom by Albert A. Michelson and Edward W. Morley in 1887, [1] [2] laying the basis for the theoretical ...
- Hydrogen Fine Structure - HyperPhysicsHydrogen Fine Structure. When the familiar red spectral line of the hydrogen spectrum is examined at very high resolution, it is found to be a closely-spaced doublet. This splitting is called fine structure and was one of the first experimental evidences for electron spin.
- Fine-structure constant - WikipediaIn physics, the fine-structure constant, also known as the Sommerfeld constant, commonly denoted by α (the Greek letter alpha), is a fundamental physical constant which quantifies the strength of the electromagnetic interaction between elementary charged particles.
