Wave And Particle Nature

Wave nature of light – Proof: light undergoes interference – Light propagates as an interdependent combination of electric and magnetic fields, each oscillating with a wavelength lambda, a frequency f and a speed c such that $c = f \lambda$ Particulate nature of light – Energy is quantized and exists in discrete packets or quanta. Each quantum of light is …

Transmission Of Light

Transmission of light – An ongoing repetitive process of scattering and re-scattering. – The speed in which light travels in the medium is the overall rate of transfer of energy across some distance of medium. It depends on the phase difference between the scattered wave and the oncoming original wave. If the resultant wave lags the original, it will result …

UY1: Steps to solving problems involving Coulomb’s Law

Identify the relevant concepts:  Coulomb’s law describes the electric force between charged particles. Set up the problem using the following steps: Sketch the locations of the charged particles and label each particle with its charge. If the charges do not all lie on a single line, set up an xy-coordinate system. The problem will ask you to find the electric …

UY1: Electric Charge & Coulomb’s Law

There are exactly two kinds of electric charge: negative and positive. Electric charge is quantized: The magnitude e of charge of the electron or proton is a natural unit of charge. Every observable amount of electric charge Q is always an integer multiple n of this basic unit e: $$Q = ne$$ Principle of conservation of charge: The algebraic sum …

UY1: Electromagnetism

This section deals with Electromagnetism at a level slightly higher than pre-university and is tailored towards first year Physics majors. Basic theories on Electromagnetism are re-visited and enhanced. Slightly more advanced theories of Classical Electromagnetism are introduced without most of the mathematical baggage. Derivations of simple Electromagnetism configurations are included as well. This is a very simple introduction to Classical …
