An atom has a number of possible quantized energy states defined by principal quantum number “n”. If it is initially in a lower state “1”, it can rise to higher states ‘2’ by absorbing a quanta of radiation (photon) of Read More …

## These 5 Tips Can Helps You Study more Effectively & defeat Procrastination

I think the best way to become an effective student is to study hard in smarter way. Don’t take me wrong, What I believe in is “Minimum Hard work with maximum smartness” is the key to become an effective student. Have Read More …

## Temporal & Spatial Coherence – LASER

In this post we will discuss ‘Temporal & Spatial coherence’ in LASER. Coherence : A wave which appears to be a pure sine wave for an infinitely large period of time or in an infinitly extended space be said to Read More …

## L-S Coupling (Russell-Saunders Coupling)

The L-S coupling is also known as ‘Russel-Saunders’ coupling after the two astronomers who first used it in studying atomic spectra emitted by stars. In atoms which obey this coupling we introduce the various perturbations in the order : (a) spin-spin correlation Read More …

## j-j Coupling -Atomic Physics

J-J Coupling is obtained in two ways : a) As a result of the stronger spin-orbit interaction, the orbital and the spin angular momentum vectors of each individual electron are strongly coupled together to form a resultant angular monnentuin vector Read More …

## Zeeman Splitting of D1 and D2 lines

Hello friends, welcome to Fullonstudy. Today we are going to discuss another important post i.e. Zeeman splitting of D1 & D2 lines. Let us consider the Zeeman splitting of resonance lines D1 & D2 of sodium lines. These lines arises Read More …

## Expalaination of Anamolous Zeeman effect

The explanation of anamolous Zeeman effect is explained by taking spin of electron. In the vector model of atom, the angular momentum L and spin angular momentum vector precess around the total angular momentum J. When the atom is placed Read More …

## Expalaination of Normal Zeeman Effect & Zeeman Shift

The noramal Zeeman effect can be explained by Classical electron theory as well as Quantum theory without taking electron spin. Now, let us explain Noraml Zeeman effect with the help of mathematical expression. Let us explain it by Classical Theory Read More …

## Noramal & Anamolous Zeeman Effect

Zeeman observed that when an atom (or light source) is placed in an external magnetic field , the atomic spectral lines it emits are splits into several polarised components. This effect of of magnetic field on atomic spectral lines is called Read More …
