Relativistic Lagrangian and equation of motion : Classical Mechanics

Relativistic Lagrangian and equation of motion Here I have tried to solve a problem in Classical mechanics which is about relativistic Lagrangian and equation of motion. Question Our problem is to show that relativistic Lagrangian give the equation of motion $F_{i}=-\frac{\partial V}{\partial \dot{x_{i}}}$ Solution From non-relativistic Lagrangian $L=T+V$ where $T$ is the kinetic energy and $V$ is […]

Photoelectric effect – brief introduction

Photoelectric effect The main idea of this article is to present a brief overview of the phenomenon called photoelectric effect. Photoelectric Effect is the emission of electrons by a substance under the action of light Photoelectric phenomenon was first noticed by Hertz when he noticed that sparks occur more readily in the air gap of

heisenberg uncertainty principle

What is heisenberg uncertainty principle? Heisenberg Uncertainty Principle or indeterminacy principle was given by German scientist Warner Heisenberg according to which position and momentum of an object can not be measured simultaneously. So if we measure the position of some particle more precisely then its momentum is measured less precisely and vice verse.Heisenberg uncertainty principle can
