## Raman Effect

In this article we will learn everything about the life of Chandrasekhar Venkat (CV) Raman, Raman Effect on Raman Spectroscopy and Raman Scattering in detail. Useful for graduate and undergraduate students. Sir Chandrasekhar Venkat Raman, also known as Sir CV Raman, was a Physicist, Mathematician and a Nobel Laureate. Venkat (his first name) was Tamil

## How to Revise Physics syllabus for JEE Main in Just 1 Month?

With JEE Main 2019 is scheduled to be conducted from 6th – 20th January 2019, you have just one month left to give your one-year preparation a sure-shot success. If you are wondering how to start your revision for JEE Main Syllabus for Physics section in order to crack the JEE Main exam 2019 in

## Meet A1689B11 : The oldest spiral galaxy ever discovered

In a collaborative attempt, astrophysicists from different institutions have found success in discovery of A1689B11 – a spiral galaxy that’s said to be the oldest discovered. The research reports an integral-field spectroscopic (IFS) observation of this gravitationally lensed spiral galaxy. It is the most ancient one till date and is calculated to be 11 billion years

## Symmetry in Physical Laws

‘Symmetry’ has a special meaning in physics. A picture is said to be symmetrical if one side is somehow the same as the other side. Precisely, a thing is symmetrical if one can subject it to a certain operation and it appears exactly the same after the operation. For example, if we look at a

## Macrostates and Microstates and their relations with Thermodynamic Probability

In this article we will define what are Macrostates and Microstates in Statistical Physics with examples and illustrations. Consider some (4, say) distinguishable particles. If we wish to distribute them into two exactly similar compartments in an open box, then the priori probability for a particle of going into any one of the compartments will

## Tunnel through the Earth

What if we make a tunnel through the earth and drop a ball or any other body into it? How would the gravity behave on the ball, and , will the ball pop-up on the other side? If yes, then how much time will it take? A question, which is usually asked in competitive exams

## Statistical Physics: Ensembles

Ensembles As a system is defined by the collection of a large number of particles, so the “ensembles” can be defined as a collection of a number macroscopically identical but essentially independent systems. Here the term macroscopically identical means, as, each of the systems constituting an ensemble satisfies the same macroscopic conditions, like Volume, Energy,

## Nanostory of Nanotechnology

This is a small story of Nanotechnology, one of the most advanced and trending topics in physics. Nanotechnology has become a widely discussed topic today in newspapers, magazines, journals, blogs and even in television ads. It’s very common that some organization announcing ‘yet another’ “nano-conference”. Nanotechnology or nanotech in short, refers to the technology of creating
