State Coulomb’s inverse-square law in electrostatics. The electrostatic force of attraction or repulsion between two stationary point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between…
The force between charged bodies is no contact force. It exists over a length, and all electrical interaction has a force embedded in it. The charges and distance between the charged bodies are the factors that determine the power and…
Who suggested the concept of a matter-wave? De Broglie suggested the concept of a matter-wave. What is the value of spin g-factor? The value of spin g-factor is 1. What is g-factor? g-factor is a dimensionless quantity used to characterise…
What is Dirac equation? Dirac’s equation is a relativistic wave equation explaining that parity inversion (sign inversion of spatial coordinates) is symmetrical for all half-spin electrons and quarks. The equation was first explained in 1928 by P. A. M. Dirac.…
What is anti-stokes scattering? When the energy of the scattered photons is more than the incident photon, the scattering is known as anti-stokes scattering. What is the use of Raman Spectroscopy? It is used to study the vibrational, rotational, and…
Raman scattering produces scattered photons with a different frequency depending on the source and the vibrational and rotational properties of the scattered molecules. Raman spectroscopy works on the principle of Raman scattering. It is used to study materials by chemists…
Define Helmholtz free energy. Helmholtz free energy is defined as the beneficial work that a system generates. Define Gibbs free energy. Gibbs free energy is defined as the highest reversible work gained by a given system. Why does an auto-encoder…
In thermodynamics, the Helmholtz free energy is a thermodynamic potential that estimates the useful work available from a closed thermodynamic system at a constant temperature. Let’s look into Helmholtz Energy and how it differs from Gibbs Energy. What is Helmholtz…
Who was the first person to study fermi paradox? First-person to study the fermi paradox is Physicist Enrico Fermi. Who developed the Drake equation? Drake equation was developed by Physicist Frank Drake. Name the stages in which biopoiesis is explained?…
We know paradox refers to the proposition or contradictory statement that when investigated may prove to be well-founded or true. There are many paradoxes in science that are hard to conclude. Some of the famous paradoxes are the fermi-paradox, twin-paradox,…
