Rogue Waves For centuries‚ mariners have spread stories about giant sudden waves which appeared out of nowhere without warning which were strong enough to capsize even the mightiest and largest ships. Several vessels—such as the S.S. Waratah‚ the M.S. Munchen‚ and the S.S. Edmund Fitzgerald—were all rumored to have been sunk by rogue waves (Walsh par. 3). Further‚ rogue waves have been blamed for ripping the bow off of a Norwegian freighter near the tip of South Africa in 1974‚ almost capsizing

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

Kinematic Derivation of the Wave Equation http://prism.texarkanacollege.edu/physicsjournal/wave-e... KINEMATIC DERIVATION OF THE HARMONIC WAVE EQUATION AND RELATED TOPICS An extremely important type of wave in physics is the harmonic wave. This is a wave consisting of propagating simple harmonic oscillations or linear combinations thereof. Attach a weight to a spring and hang the spring so the weight is free to move. Then lift the weight straight up and release it; it will oscillate up and down

Electromagnetic Waves Although you might not know it you’re constantly surrounded by thousands of electromagnetic waves every day. Sunlight and x-rays are only two types of electromagnetic waves‚ other types are: radio wave‚ infrared rays‚ ultra-violet rays and gamma rays Nature of an electromagnetic wave Electric and magnetic fields are not made up of matter. An electromagnetic wave consists of an electric and magnetic field and doesn’t need a medium to exist. They are the regions through

Personal Response on Sexual Identity You go through your life making choices and decisions but not thinking of exactly why you were making the choices that you made. Before this class I just figured that I mad the decisions I made because it was what I wanted at the time. Since I have taken this class I have found that the decisions that you make are based on what is called a value system. According to Rathus‚ Nevid‚ and Fichner-Rathus (2011)‚ the value system has to do with legalism

Personal Response to Wilfred Owen One of Wilfred Owen’s poem is Dulce et Decorum est. The title of this poem is roughly translated to: It is honorable and beautiful to die for your country‚ the poem itself basically speaks of how this is a lie. It takes you through a small story at the end of which it explains in gruel poetry the death of a soldier with effective language that helps inspire fear “And watch the white eyes writhing in his face‚ His hanging face‚ like a devil’s sick of sin;” I believe

my chair out of his office‚ and headed for the boardwalk. The sun is setting; the ocean waves are crashing against the shore pounded with the rhythm of my beating heart. Spending the rest of my life in a wheelchair meant giving up the things I love‚ no dancing‚ no high heels‚ no hiking‚ no beach-combing. As I watched as the waves rose up‚ curled‚ then crashed; drew back into the sea. With each crash‚ the waves seemed to pull a piece of my life out to sea‚ saying‚ no more. . . no more. ... I couldn’t

Electromagnetic waves in space See the book “Optics” by Hecht sections 3.2 and 3.3 Speed of light: EM waves travel in a vacuum with speed c = c = 299‚792‚458 ms-1 exactly They are transverse waves with (vector) E and B field orthogonal to each other‚ for this section bold indicates vector quanties. When far from the source (many wavelengths) the E and B fields are in phase The vector E x B points in the direction of motion Travelling waves can be written as E = E 0 ⋅ ei ( kx −ωt ) and B = B 0 ⋅ ei

1.0 What Causes the Tides Tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the earth and the moon. Tides are the cyclic rising and falling of earth’s ocean surface caused by the tidal forces of the moon and the sun acting on the earth . Tides cause changes in the depth of the sea and produce oscillating currents known as tidal streams‚ making prediction of tides important for coastal navigation. The strip of seashore
