Electron Mass
In physics, the electron mass or mass of electron or electron rest mass one of the fundamental constants and is defined as the mass of a stationary electron. Denoted by me. The value of electron mass is also known as the invariant mass of an electron. Electron Mass Value Electron mass is sometimes termed as…

Rydberg Constant
In the science of spectroscopy, under physics, the Rydberg constant is a physical constant relating to atomic spectra. It is denoted by R∞ for heavy atoms and RH for Hydrogen. Rydberg constant was first arising from the Rydberg formula as a fitting parameter. Later Neils Bohr has calculated it from fundamental constants. Rydberg Constant Value R∞ and electron spin g-factor…

Gas Constant
The gas constant is a physical constant denoted by R and is expressed in terms of units of energy per temperature increment per mole. It is also known as Ideal gas constant or molar gas constant or universal gas constant. The gas constant value is equivalent to Boltzmann constant but expressed as the pressure-volume product instead of…

Stefan-Boltzmann Constant
In Physics, Stefan-Boltzmann Constant also known as Stefan’s constant is a physical constant. It is the constant of proportionality in Stefan-Boltzmann law of Blackbody radiation. Stefan Boltzmann Constant is denoted by Greek letter σ. This physical constant was formulated by Josef Stefan during 1879 and derived by Ludwig Boltzmann during 1884. Stefan Boltzmann Constant Value The…

Neutron Mass
What are neutrons? It is a subatomic particle. Neutron is the composition of 1 up quark and 2 down quark and comes under the family of fermions. It is denoted by n or nº. The neutron mass is slightly higher than the proton mass. The charge of the neutron is null, which implies that neutron is…

Compton Wavelength
In physics, the Compton wavelength is the quantum mechanical property of a particle and is defined as the wavelength of the particle equal to the wavelength of the photon with same mass. It is well explained through the process called Compton scattering. The standard Compton wavelength is denoted by Greek letter λ (Lambda) measured using…

Bohr Radius
In atomic, physics, Bohr Radius is a physical constant, expressing the most probable distance between the electron and the nucleus in a Hydrogen atom in the ground state. Denoted by ao or rBohr. Due to his prime role in building the Bohr model, This physical constant is named after him. Bohr Radius (ao or rBohr) The value…

Gravity Formula
We know gravity is the fundamental force and is the elemental concept of Physics. Gravity or gravitational force is the contribution of the great scientist Sir Isaac Newton. We know that dropping an apple from a tree was the reason for the inception of the Law of Universal Gravitation. In this session, let us learn…

Heat Loss Formula
Heat Loss Decrease of heat existing in space, resulting from heat transfer through roof, walls, windows and buildings surfaces or other factors is known as heat loss. Heat loss is determined by multiplying the values of the surface area, the difference in temperatures of indoors and outdoors and the value of heat loss of…

Friction Formula
Friction is the hindering force that comes into play when two items are interacting with each other. Friction formula is typically given as Ff = μFn The numeric’s are, the magnitude of friction is Ff , the coefficient of friction is μ and the magnitude of the normal force is Fn. The Normal force is equivalent to the weight…
