seven different waves. The waves are in the order of how big the wavelength is and its frequency‚ from the biggest to the smallest: Radio waves‚ Micro waves‚ Infrared‚ Visible light‚ Ultra Violet‚ X-rays and Gamma rays. Each of them has their own special use in everyday life. For example‚ to turn on a TV you need to use Radio waves‚ to heat your food you use Microwaves and X-rays are used to look into people’s bodies. Some waves‚ like Radio waves can be as big as a building or waves like Gamma rays

BAND THEORY OF SOLIDS According to quantum free electron theory of metals‚ a electron in a metal experiences constant(or zero) potential and free to move inside the crystal but will not come out of the metal because an infinite potential exists at the surface. Bloch Theorem: According to this theorem‚ the periodic potentials due to the positive ions in metal have been considered. (i.e. the electrons moves in a periodic potential provided by lattice). If the electron moves through these ions‚

sound waves Sound is a series of compression waves that moves through air or other materials. These sound waves are created by the vibration of an object‚ like a radio loudspeaker. The waves are detected when they cause a detector to vibrate. Your eardrum vibrates from sound waves to allow you to sense them. Sound has the standard characteristics of any waveform. Sound is a waveform that travels through matter. Although it is commonly in air‚ sound will rapidly travel

Characteristics and Nature of Waves In physics‚ a wave is a disturbance that travels through space and time‚ usually accompanied by the transfer of energy. Waves travel and the wave motion transfers energy from one point to another‚ often with no permanent displacement of the particles of the medium—that is‚ with little or no associated mass transport. They consist‚ instead‚ of oscillations or vibrations around almost fixed locations. For example‚ a cork on rippling water will bob up and down

of an electronic wave packet in the unifonn field in the interelectrode space of the vacuum photodetector is investigated. It is shown that the dimensions of such a packet must be of an order or more then one micron. It is shown that such localized charges can give rise to abrupt pulses of the current in the external circuit of the photodetector. The determination ofparameters of such packet by powerful laser pulse scattered with is discussed. The motion of one-electron wave packet in the nonuniform

The story‚ “Adventure of a Speckled Band”‚ written by Sir Arthur Conan Doyle‚ portrayed a secretive detective story based on Sherlock Holmes. The story consisted of numerous characters that deprived in the passage. To illustrate‚ the main character‚ Sherlock Holmes‚ played a major role; following Dr.Watson‚ Dr.Roylott‚ as well as Helen Stoner‚ who were all incorporated into the unraveling mystery. In Stoke Moran‚ England‚ the perceptible situation had begun during the time period of April 1883.
