Schrodinger time dependent wave equation derivation

Schrodinger time independent wave equation derivation Schrodinger time dependent wave equation derivation Consider a particle of mass “m” with velocity “v” and under the influence of potential energy (P.E) which is represented by V(r) .The total energy of the particle is the sum of potential energy (P.E) and kinetic energy (K.E) which is given by:       This is ...

time independent schrodinger wave equation

Schrodinger time dependent wave equation What is schrodinger wave equation? In classical mechanics the motion of a body is given by Newton’s second law of motion.But elementary particles like electron,protons and photons possess wave properties as well,therefore another equation instead of Newton’s second law equation ( F=ma) is required for describing their motion.The new equation must take into account wave ...

What is difference between electromagnetic waves and matter waves?

Difference between electromagnetic waves and matter waves in tabular form Electromagnetic waves     Matter waves These waves have electric and magnetic fields associated with them. Matter waves have no electric and magnetic fields associated with them. These waves can easily pass through vacuum. These waves cannot pass through vacuum.                     ...

Dual nature of matter and De broglie wavelength

What is dual nature of matter? Our mental views of wave and particles are drawn from familiarity with very large scale objects such as tennis balls and ocean waves.Like paul Davies ,physicist and science writer it is impossible to visualize a wave particle so do not try what then are we to do? Neil Bohr views According to Neil Bohr ...

uses and applications of x rays waves in everyday life

Uses of gamma rays in everyday life 1:Radio Therapy X-rays kill the diseased tissues of the body.Hence they are used to λ cure intractable skin diseases,malignant tumours etc.If the affected part is superficial soft rays are applied and for deep seated organs hard rays are used. 2:Engineering Because of their high penetrating power they are used ti investigate the structure of ...

Plasma physics and controlled fusion energy

Plasma physics definition “The branch of physics which deals with the study of the properties of plasma is known as plasma physics.” Plasma definition A highly ionised gas is regarded as a fourth state of matter called the plasma state.It is regarded as fourth state of matter since it is not solid,liquid or gas in usual sense. How plasma is ...

Is an electron a particle or a wave?

In 1924,de Broglie proposed that particle acts as a wave and wave acts as a particle. Davisson and Germer experimentally confirmed the wave nature of electron.They showed that electrons are diffracted from metallic crystal in the same manner as x-rays and other wave.Hence electrons show wave like properties.J.J Thomson while measuring e/m of electron showed that electron is a particle.Thus ...

Does a photon have a de Broglie wavelength?

Yes a photon has de Broglie wavelength.In 1924,Louis de Broglie proposed that a particle must also act like wave,in silmilar way,wave behave like particles. In de Broglie hypothesis an electromagnetic wave is the de-Broglie wave for a photon moving with speed c.According to de-Broglie ,the wavelength of the photon is given by the relation: λ = h/p Where P is ...
