matter waves

De-Broglie Relationship - De-Broglie noted that according to the theory of relativity, the role played by momentum 'P' and the energy 'E' of the particle is done by angular frequency ' w ' and the propagation vector 'k' of a wave. According to Einstein relation E = mc 2 Where 'm' is the m..

Question: Which of the following quantities is transferred during wave propagation? 1. Speed 2. Mass 3. Matter 4. Energy Answer: ..

Light is a form of energy produced by luminous objects. Light can travel through vacuum. Light can penetrate through transparent materials but cannot pass through opaque objects. Light travels in a straight line in an optically homogeneous medium. Light bounces back when made to fall ..

. After some time the second bob starts oscillating, then bob 3 and so on until the last bob starts oscillating. How did the disturbance travel from the first to the seventh bob? When the first bob is pushed it gains some energy and starts oscillating. This oscillation produces a disturbance in the..

Elementary Idea of Electron Microscope - 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 c..

>Thus, the wavelength of material particles, l is: This equation is known as de-Broglie's equation. where p stands for the momentum (mv) of the particle. Since h is constant, l 1/Momentum. It means that the wavelength of a particle in motion is inversely proportional to its momentum. The concept of..

Satellite Communication - It is mainly done through geostationary satellites. These satellites are fitted with special devices. These devices can receive signals from an Earth station and transmit them again in different directions. These special devices are called transponders. A TV transmitter on..

Summary - 1) Non-invasive diagnostic techniques are those that can be applied without penetrating the skin. 2) X-rays have a remarkable ability to penetrate matter. They help to provide detailed images of dense parts of the body like bones. 3) The photographic image produced by x-radiatio..
