What is Electron Holography?
Electron holography is an application of holography procedures to electron waves quite than light waves. Electron holography was invented through Dennis Gabor to enhance the resolution and ignore the aberrations of the transmission electron microscope. Nowadays it is usually used to study electric and magnetic fields within thin films, as magnetic and electric fields can move the phase of the interfering wave passing by the sample. The principle of electron holography can as well be applied to interference lithography.
In an electric field rate of change of potential with distance is called as potential gradient. It is a vector quantity and its direction is differing to that of electric field. Po
what are characteristics of resistances
It is defined as the magnetic lines of force per unit area of the pole face. B=φ/A where φ is the magnetic lines of f
Focal length of convex lens is 0.1 m. A liquid lens is formed between a plane surface and one face of this lens of radius of curvature 0.12m. The converging combination formed is f
A bat emits a sound whose frequency is 142 kHz. The speed of sound in air at 20.0°C is 343 m/s. However, the air temperature is 35°C, so the speed of sound is not 343 m/s. Find the
Thermonuclear reactions: The fusion reactions which require extremely high temperatures are called thermonuclear reactions. The most important thermonuclear reactions take plac
What is Illumination? A body that gives off light is called luminous, like all those glow-in-the-dark toys, and a body that gives off light when it is heated is called incandes
