electron wavelength

De-Broglie Wavelength of an Electron - Similar to the crystal diffraction patterns produced by X-rays, even the beam of electrons of appropriate momentum could produce crystal diffraction pattern. Imparting the desired momentum to the electron obtained by the..

In optical microscope, the ray of light can be bent by a lens system. By placing the object and the lens system in such a way, we control the direction of the ray to get a magnified image of the object. Since as 'electron' carriers charge it is possible to change the direction of a e..

When light of sufficiently small wavelength is incident on a metal surface, electrons are ejected from the metal. This phenomenon is called as 'photoelectric effect' and the ejected electrons are called as 'photoelectrons..

6. Calculate the wavelength of the spectral line when the electron in the hydrogen atom undergoes a transition from 4 t h energy level to 2 n d energy level. What is the colour of the radiatio..

>Similar to light, matter also manifests itself in the form of particles as well as waves. Compton effect, and Davison and Germer's experiment stand as evidence for dual nature of matter. If an electron acts as a wave, its wavelength is calculated to be Davison and Germer showed..

Photodiode is essentially a P-N junction which works on the basis of electric conduction from light. When light falls on such diodes and if the wavelength of the light is such that the energy of the photon is sufficient to break a valence bond, a new hole - electron pairs ..

The Photoelectric Effect - There are three ways in which electrons eject out of a material. They are (i) Thermionic emission (ii) Field emission (iii) Photo electric emission In all the above cases, energy is given to the material but in different forms. If given in the form of heat it is..

One can understand atomic spectra if one knows the concept of atomic energy levels. The movements of electrons from one level to another causes the spectra. The work of a spectoscopicst is to find the energy levels of an atom from the measured values of the wavelengths of ..
