Notes Various stages of star formation Star formation is a complex process that involves the gravitational collapse of a region within a large molecular cloud, leading to the formation of a protostar and, eventually, a main-sequence ...
Notes Wave function The wave equation is a partial differential equation that describes how waves propagate over time and space. It is a fundamental equation in physics and is used to model a ...
Notes Scattering of electromagnetic radiation The scattering of electromagnetic radiation refers to the process by which electromagnetic waves deviate from their original path due to interactions with particles or obstacles in their path. This β¦
Notes Hamiltonian Formulation The Hamiltonian formulation is a mathematical approach in classical mechanics and quantum mechanics that provides an alternative description of the dynamics of a physical system. It is named after β¦
Notes Relativistic Hamiltonian for a charged particle The relativistic Hamiltonian for a charged particle in an external electromagnetic (EM) field can be derived from the relativistic Lagrangianwhere vector P = generalised momentum.The generalized β¦
Notes Equation of motion using Hamiltonian principle The equation of motion in covariant form can be obtained from the Lagragian by using Hamiltonian principleConsider the action integralIn order to write action in invariant form, we ...
Notes Thomas Fermi Method The Thomas-Fermi model is a semiclassical approach used in quantum mechanics to describe the electronic structure of atoms. It was developed independently by Llewellyn Thomas and Enrico Fermi in the β¦
Notes Normal Zeeman Effect and Anamolous Zeeman Effect The Zeeman effect refers to the splitting of spectral lines observed when the light emitted or absorbed by an atom is subjected to a magnetic field. The normal Zeeman effect ...
