Even though Niels Bohr’s quantum theory of spectra was regarded as one of the most revolutionary and successful theory of atomic dynamics, it was limited in the following ways:
The discovery of a temperature seen by an accelerated fiducial observer adds a new dimension to the equivalence principle. Identical thermal effects can be expected to happen near the horizon of a very massive black hole. Nonetheless, in … Read More
The equivalence principle is one of the laws of nature and it is connected with the nature of gravitation. In general relativity theory, the equivalence principle states that a gravitational field is locally equivalent to an accelerated frame. To be … Read More
Electron beams are capable of providing crystallographic information about nanoparticle surfaces and can also be used to produce images of the surface, and they play this role in electron microscopes.
In a transmission electron … Read More
Einstein special theory of relativity is based on two assumptions:
Though quantum mechanics is a dynamical theory much like Newtonian mechanics, there are key differences between the two. In Newton’s mechanics, the state of a particle at t = 0 is specified by giving its initial position x (0) and … Read More
Symbolized by the letter n, this number describes the shell that an electron resides in. An electron “shell” is a region of space around an atom’s nucleus that electrons are allowed to exist, corresponding to the stable “standing wave” patterns … Read More
In 1935 Yukawa proposed in his paper that there exist a meson field, that is, a field that is different from the electromagnetic field, whose quanta, the mesons have a finite mass, which is coupled to protons and neutrons in … Read More
Compton Effect was a key experiment that provided the most direct evidence for the particle nature of radiation. Arthur Holly Compton, an American Physicist discovered that, radiation of a given wavelength (in the X-ray region) sent through a metallic foil … Read More
When a body is heated, it seen to radiate; in equilibrium the light emitted ranges over the whole spectrum of frequencies v, with a spectral distribution that depend on the frequency or equivalently on the wavelength of light λ… Read More
