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
Pulsed lasers can be used in the synthesis of nanoparticles of silver. Silver nitrate solution and a reducing agent are flowed through a blender like device. In the blender there is a solid disk, which rotates in the solution. The … 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
Generally all particles other than field particles can be classified into two broad categories:
Particles that interact through the strong force are known as hadrons. The two classes of hadrons, mesons and baryons are distinguished by their … 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
Nanoparticles can be produced by decomposing solids at high temperature having metal cations, and molecular anions or metal organic compounds. This procedure is termed to as Thermolysis. For instance, small lithium particles can be made by decomposing lithium azide, LiN… Read More
The theory of electromagnetism was developed by physicist James Clerk Maxwell. According to his theory, an alternating current would set up fluctuating electric and magnetic fields in the region surrounding the original disturbance. Furthermore, these waves were predicted to have … Read More
The lithographic methods used to make silicon chips for computers are approaching their limits in reducing the sizes of circuitry on chips. Nanosize architecture is becoming more cumbersome and more costly to make. This has motivated an effort to synthesize … Read More
While the existence of the photoelectric effect can be understood within the framework of classical electromagnetic theory since it was known that there were electrons in metals and one could envisage them to be accelerated by absorption of radiation, the … Read More
