Namee: Paul G. Zamora (Homework in Performance Techniques) Sound Waves- A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air‚ water‚ or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration‚ such as a ringing telephone‚ or a person’s vocal chords. The vibration disturbs the particles in the surrounding medium; those particles disturb those next to them

STANDING WAVES A string attached to a turning fork is set vibrating at the same frequency as the tuning fork. The length and tension in the string are adjusted until standing waves are observed on the string. By knowing the tension in the string and the wavelength of the standing waves‚ the frequency of oscillation of the string and thus‚ the tuning fork is found. This value is then compared to a strobelight determination of the frequency. THEORY If transverse waves of constant

Ocean Waves A wave is a periodic disturbance in space and time‚ possibly transferring energy to or through a space-time region. Have you ever ridden a wave in the ocean? Ocean waves travel on the surface of the water. You can see them and you can feel them. As you swim through the water‚ you can even make your own waves. The winds cause waves on the surface of the ocean (and on lakes). The wind transfers some of its energy to the water‚ through friction between the air molecules and the water molecules

SINE WAVE Sine wave: Sine wave is the most fundamental form in analog signal. When any communication process will be analog process then the data must be converting into analog signal & a sine wave is the common form of analog signal. A sine wave changes over a course of cycle which is constant and continuous. A sine wave represent in graphically where time in X axis & value in Y axis. [pic] Parameters; A sign wave have three parameter

Korean schoolchildren in North and South learn that Japan invaded their fiercely patriotic country in 1905‚ spent forty years trying to destroy its language and culture‚ and withdrew without having made any signicant headway. This version of history is just as uncritically accepted by most foreigners who write about Korea. Yet the truth is more complex. For much of the country’s long history its northern border was fluid‚ and the national identities of literate Koreans and Chinese mutually indistinguishable

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

Korea Calendar As in many Asian countries‚ Korea uses both the solar and lunar calendars‚ and celebrates holidays based on both. The country uses one time zone and is 9 hours ahead of GMT‚ the same as Japan. Most Koreans work Monday through Friday and then a half day on Saturday mornings. Usual business hours are 9:00-6:00 during the week and 9:00-1:00 on Saturday. During national holidays‚ government offices and most businesses are closed‚ although many private store keepers and large department

the first Korean music video that got 100 million views on YouTube. The Korean singer/rapper Psy then became an international star that reached the number two spot on the American Billboard Charts and number one on the Chinese music charts. He was even invited on the Ellen Show to perform his dance next to Britney Spears and Ellen Degeneres herself. These are prove that the Korean Wave (or Hallyu in Korea) is gaining more recognition not only in Asia‚ but also the world. With Korean culture in

radio stations broadcast. A radio wave (radiating electric field) propagates out from the source‚ traveling at the speed of light. The source‚ for example an antenna‚ creates oscillating electric(E)/ magnetic(B) fields. These fields are perpendicular not only to each other but to the direction of the traveling wave‚ and travel away from the antenna. The electromagnetic wave is‚ therefore‚ a transverse wave. The electric/ magnetic fields store the energy of the wave. Basically‚ the oscillating current
