What is an Atomic Unit of Length?
The atomic unit of length (bohr radius ≈ 0.529 Å) represents hydrogen atom's electron orbit radius. Used in quantum calculations where 1 a.u. equals the Bohr radius, simplifying equations in atomic physics.
What is a Light Year (ly)?
The light year is a unit of distance that represents how far light travels in one year in a vacuum. It is commonly used in astronomy to describe interstellar distances.
