Introduction In thermodynamics and statistical mechanics, we often study gas molecules inside a container. In such a case, it is impossible to study each molecule separately. Indeed, even in a single mL of gas, there are almost an uncountable number of gas molecules. Thus, instead of working with individual molecules, we focus on them as a system. When we work with systems, we describe them by picking a range of velocities and trying to figure out the possible number of molecules that are moving with that velocity. This is where Maxwell-Boltzmann Distribution comes in handy. What Is Macrostate? To understand ... Read More

Introduction Measurement denotes the comparison of an unknown quantity with a known quantity. It is the measure of quantity. Length, mass, time, electric current, temperature, amount of substance, and luminous intensity are the seven fundamental quantities. There are many systems of units used such as the KGS system, CGS system, and International SI system. Different systems assign different units for basic elements. If the quantity has only magnitude then it is called a scalar quantity. Example mass, distance, time, etc. If the quantity has both direction and magnitude then it is called a vector quantity. Example velocity, displacement, force, etc. ... Read More

Introduction Bell’s theorem is a very interesting concept of modern science and philosophy. The strange realm of quantum mechanics is often complicated, and at times, incalculable. More importantly, investigating quantum mechanics often leads us to the interface between the world of science and philosophy. You might not know this, but these two topics are closely related. It might interest you to know that some of the most prominent paradoxes in Physics were proposed by philosophers, not physicists or scientists. Achilles and the Tortoise is a famous example of the latter. Another concept that, in a way, bridges the gap between ... Read More

Introduction Compton shift explains the Compton scattering of electromagnetic radiations. Visible light is electromagnetic radiation and is the only part of the electromagnetic spectrum that can be visible to the human eye. Photon is the basic unit of light. It is a quantum of energy or energy packet in electromagnetic radiation. Albert Einstein explained the fact of discrete energy packets during the transmission of light. And it was first named a photon by Gilbert N. Lewis. They are always in motion and move with the speed of light in a vacuum. All electromagnetic energy is made up of photons. ... Read More

Introduction Mechanics originated dates back from 384 B.C. to 322 B.C. The ancient Greek philosophers were the first to propose the principles that govern nature. Aristotelian mechanics was considered the main theory of mechanics until the medieval age. Today, the principles of Mathematical mechanics find application in our day-to-day activities. Let’s explore Mechanics in more detail. What is Mechanics? Mechanics is one of the most important branches of Physics. It helps us in observing and analyzing the motion of any physical object under the influence of force or when the object is at rest (F=0). Mechanics helps us to establish ... Read More

Introduction Atoms are a basic unit of material. According to the Bohr atom model atoms contain a small central core called a nucleus which is full of positive charges. Electrons are round about the nucleus in a particular circle named orbits. The circular path is maintained by the centripetal force derived from the electrostatic force between the electrons and the nucleus. Radiation is a process of transmission of energy from one object to another through the medium or space. It can be ionizing or non-ionizing, which depends upon the energy of the radiation. Ionizing radiation has an energy of ... Read More

Introduction We know that the structure of atoms is the same as the solar system. In the solar system, the sun is the center and other planets revolve around it in a definite path same as The atom nucleus at the center and electrons revolve around it. However, we found that planets also rotate at their fixed position. This discovery leads to the rotation and spinning of electrons at a fixed position. That’s why scientists started to research and found that electrons also rotate. In 1925 two scientists Goutsmit and Ulhenbeck derived the idea that an electron also has angular ... Read More

Introduction Quantum physics is a branch of physics that possibly explains how everything in nature works in real-time. As nature around us is made up of the particles, matter and energy, quantum physics explain the way these things work to support the working principle of nature. Quantum physics also explains the way particles make matter and force and how they react with each other in real-time. In simple words, the phenomenon of quantum physics describes the way atoms work in real-time. What is quantum physics? Quantum physics can be defined as the foundational basis of material science that is ... Read More

Introduction Quantum mechanics is a scientific phenomenon that happens everywhere in daily lives starting from lasers to integrated circuits and many more. In real-time, many technologies rely upon quantum effects to work properly. Quantum mechanics is also crucially important for understanding the way individual atoms are joined by covalent bonds, especially while forming molecules. Real-time components like lasers, telecommunications, magnetic resonance imaging, GPS and atomic clocks use the technology of quantum mechanics for functioning properly. What is Quantum Mechanics? Quantum mechanics can be defined as a branch of physics that deals with the behaviour of light and matter on ... Read More

Introduction Johannes Rydberg, a Swedish physicist introduces the Rydberg formula which represents the fundamental constant of the atomic physic. It describes the frequencies or wavelengths of light in different series which is related to the spectral line. Especially it emphasizes those which are emitted by hydrogen atoms from the Balmer series. The standard of this constant is generally founded on a premise. A nucleus of an atom generally emits light which is extremely massive in comparison to the electron which is single orbiting. The certain value of Rydberg constant is 10, 973, 731.56816 per meter. Rydberg Constant and its explanation ... Read More
