Mid-1880 Austrian theoretical physicist Ludwig Boltzmann using the laws of thermodynamics for an expansion of cylinder with a piston at one end that reflects the blackbody

No matter how small the frequency of the light, no matter how small the intensity, if one waits long enough, electrons will accumulate enough electromagnetic radiation to overcome

• The time dependence of the SE can often be factored out of the equation leaving the so-called time-independent Schrödinger equation, which determines the allowed values of

This wave function is a superposition of plane waves with different momenta p and describes a free particle localized in the space A wave packet is a group of waves with

Because a matter wave does leak into the walls the wavelength λ for any given quantum state is greater when the electron is trapped in a finite wave than when it is trapped in

n=1: ground state, i.e., the lowest energy orbit of the hydrogen atom The orbital energy E n is

In 1913 Niels Bohr creates a model that includes both classical and non-classical (quantum mechanics) ideas and attempts to explain why hydrogen atom is stable.. The most

orbital 2s, volume probability density for the hydrogen atom in the quantum state with n=2, l=0, m l =0; the gap in the dot density pattern marks a spherical surface over which
