The Compton wavelength is a quantum mechanical property of a particle. The Compton wavelength of a particle is equivalent to the wavelength of a photon ... more
In physics, mass–energy equivalence states that anything having mass has an equivalent amount of energy and vice versa, with these fundamental quantities ... more
The refractive index is used for optics in Fresnel equations and Snell’s law; while the relative permittivity and permeability are used in ... more
The Schwarzschild radius (sometimes historically referred to as the gravitational radius) is the radius of a sphere such that, if all the ... more
The drift velocity is the average velocity that a particle, such as an electron, attains due to an electric field.
In terms of the basic ... more
