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

Before beginning our research on radio waves‚ to us‚ radio waves were just waves going through the atmosphere‚ carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves‚ and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves‚ which represent voice and other

order to present their experiences of Korean Wave‚ this paper will be divided into four sections. The first section will describe demographic characteristics of the Korean Wave group in Asia. The second section is a literature review refering to the cultural background of Korean Wave including Korean pop music‚ drama‚ food and so forth. This is followed by an interview conducted with Helen and Hana giving information about their experiences of Korean Wave. The final section will state some steretyping

to point through a medium is called a ___. a. period b. periodic wave c. wavelength d. pulse Answer: D A wave is a continuous and repeating disturbance of a medium and a pulse is a single disturbance. 2. If the particles of the medium are vibrating to and fro in the same direction of energy transport‚ then the wave is a ____ wave. a. longitudinal b. sound c. standing d. transverse Answer: A In longitudinal waves‚ particles of the medium vibrate to and from in a direction parallel

Seismic waves‚ which are waves of energy that travel through the earth‚ and are a result of an earthquake‚ explosion‚ or a volcano that imparts low-frequency acoustic energy. There are two types of seismic waves‚ Body waves and surface waves. Body waves travel through the interior of the earth. Surface waves travel along the earth’s surface and through water. Seismic wave fields are measured by a seismograph‚ geophone‚ hydrophone or accelerometer. These are used to measure earthquakes. When

After the 4th wave‚ just one rule applies: TRUST NO ONE. Now it’s the dawn of the 5th wave‚ and on a lonely stretch of highway‚ Cassie runs from Them: the beings who only look human‚ who roam the countryside killing anyone they see. Who have scattered Earth’s last survivors. To stay alone is to stay alive‚ Cassie believes

Surface Waves: Understanding its movements I. Introduction We treat here an important wave phenomenon‚ the surface wave. It occurs in many physical systems both mechanical and electromagnetic. Mechanical surface waves can exist at the interface between two media with different densities such as the oceans and air. Ordinary sea waves and tsunamis are surface waves. Seismic events can produce both longitudinal and shear waves at the earth’s surface‚ resulting in earthquakes. Electromagnetic surface

entertainment industry. Since 1990s‚ the phenomenon “Hallyu” mostly recognized as “Korean Wave” spread out far away from its mother land and surprisingly made such a positive impression. There are millions of fans of k-pop over the whole world and in the last three-four years popularity of Korean pop-culture reached Kazakhstan. Kazakhstani channels show various TV dramas and a lot of music videos. So‚ what is the reason of k-pop’s popularity‚ is it because Korean culture has unique style‚ which differs
