Standing wave Standing waves in a string — the fundamental mode and the first 6 overtones. A standing wave‚ also known as a stationary wave‚ is a wave that remains in a constant position. This phenomenon can occur because the medium is moving in the opposite direction to the wave‚ or it can arise in a stationary medium as a result of interference between two waves traveling in opposite directions. In the second case‚ for waves of equal amplitude travelling in opposing directions‚ there is on

REVIEW of The Wave by Morton Rhue This story‚ based on a true incident that occurred in a high school in California‚ demonstrates how easily a group can lose its freedom without even realising it. It all began when their history teacher‚ Mr. Ben Ross‚ let them watch a movie on how the Nazis in World War 2 tortured the people who opposed them. To give them a clearer picture‚ he decided to them in the situation itself. He then introduced an organisation‚ The Wave‚ and its motto‚ "Strength

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

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

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

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

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

Water Waves By Anna Introduction Water waves have been around for years; learning about water waves can help you understand the outside world. Water waves can be used in many ways‚ but they can also be harmful‚ too. When were they discovered? Water waves have been around since the creation of the earth‚ but Isaac Newton came up with a theory; after studying waves in about 1687. What is the biggest wave? In 1958 the biggest tsunami wave was recorded. How much harm can water waves really
