### FAQ

What is Radius of the Orbit?
The Radius Of The Orbit formula is defined as the radius of the fixed orbit as the electron revolves around the nucleus of the atom and is represented as r = (n*h)/(2*pi*m*v) or radius = (Quantum Number*Plancks Constant)/(2*pi*Mass*Velocity). Quantum Number describe values of conserved quantities in the dynamics of a quantum system, Plancks Constant is the quantum of electromagnetic action that relates a photon's energy to its frequency, Mass is the quantity of matter in a body regardless of its volume or of any forces acting on it and Velocity, in physics, is a vector quantity (it has both magnitude and direction), and is the time rate of change of position (of an object).
How to calculate Radius of the Orbit?
