Electromagnetic Theory

1. Lorentz force law:

$F=q[\vec{E}+\vec{v}\times \vec{B}]$

2. Electric field due to infinite charged sheet:

$\vec{E}=\frac{\sigma}{2 \epsilon_{o}}$

    The World Of Quantum Mechanic " Those who are not shocked when they first come across quantum theory cannot possibly have understood it." - Niels Bohr 1.             Introduction: Quantum mechanics is totally a different field of science filled with lots of maths, uncommon things and mind blowing phenomena. The word quantum means 'the smallest unit' of some particular physical objects or properties like energy for instance.It is one of the most powerful subject of physics due to its vast and enormous applications in the modern digital, medical, astronomy, almost everywhere and i will tell you later on how . 2.     What actually is quantum mechanics? "In the simplest terms, quantum mechanics is a branch of physics in which we study about the wave-particle dual nature of microscopic particles and their dynamics". I know it's quite fuzzy to get it but don't worry i will simplify this explanation as much as possibl...

Quantum Tunneling: Penetrating the Impenetrable Barrier Quantum Tunneling: Penetrating the Impenetrable Barrier By Md Irfan | 2nd Year Physics (Hons) Presented on National Science Day – 28th February 2023 Introduction Quantum mechanics has revolutionized our understanding of nature at its most fundamental level. Among its most intriguing consequences is the phenomenon of quantum tunneling —a process that defies classical intuition and permits particles to traverse energy barriers that should be insurmountable. This principle underlies a broad spectrum of physical phenomena, from nuclear fusion in stars to the operation of nanoscale devices, and has far-reaching implications in both theoretical physics and practical technology. Theoretical Foundation: Mathematical Framework Let us examine the situation of a non-relativistic particle of mass m, approaching a potential barrier of height V_0 and width a. Classically, if the energy E Potential Profile \[ V(x...
