davison and germer experiment which crystal is used

The first experimental proof of the wave nature of electron was demonstrated in 1927 by two American physicists C.J Davison and L.H Germer. The basis of their experiment was that since the wavelength of an electron is of the order of spacing of atoms of a crystalh..

Take a glass tube with graduation from 0 to 100 ml. Close the lower end by a rubber stopper, and pour into it a saturated solution of sodium hydroxide up to the 0 mark. Add a few crystals of white pyrogallol (about 0.5 g) into the glass tube. Now close the upper end with a glass stopper,..

>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..

/c to photons of energy h u . The elastic scattering of a photon from an electron at rest can be worked out by using the principles of conservation of energy and conservation of momentum. The discovery in 1905 of the dual nature of light was followed by the discovery of dual nature of ma..

/p. This is de Broglie wave equation. De-Broglie's hypothesis attributing a dual particle-wave character to matter appears very strange at first sight. Since it is very much against the direct evidence of one's senses at the macroscopic level. But at the level of the atom, the behavior of matter ha..

When unpolarised light is passed through a tourmaline crystal cut with its face parallel to its axis AB, only those vibrations of light pass through which are parallel to AB and all others are absorbed. The light intensity, therefore, is reduced. The emergent light from the first cry..

. At the points where resultant intensity is maximum, interference is said to be constructive. At the points where the resultant intensity is minimum, interference is said to be destructive. Thomas Young's double slit experiment was the first to demonstrate the phenomenon of interference ..

. But he was still looking for a friend and soon he found a small baby Christopher Harry Winters, who was of the same size as he was and completely naked. He learnt that Winters was an ungrown specimen of the senior species of earth. When winter's mother picked up the baby, waves of love and matern..
