    390 words
    Savage Seas The Wave Machine The wave machine is a simulator that will allow you to create an ocean wave and determine its height. Most ocean waves are formed when the wind blows across the water's surface. The wave height is determined by three factors: wind speed, fetch, and duration. Wind Speed In 1805, Sir Francis Beaufort, observing the effects of wind speed upon the sea, devised the Beaufort Wind Scale. Though wind speed is not the only factor in determining wave size, the Beaufort scale r...
  • Subduction Zone Waves Earthquakes Quakes
    854 words
    Earthquakes are vibrations produced in the earth's outer layer, or crust, when forces pushing on a mass of rock overcome the friction holding the rock in place and blocks of rock slip against each other. The vibrations can range from barely noticeable to very destructive. There are six types of shock waves. Two are classified as body waves which means they travel through the earth's interior and the other four are surface waves. The waves are changed by the rock types or formations they hit. Pri...

    Lab essay # 5 There are several different heart problems that show up as an abnormal EKG reading. For example, a heart block can occur when there is a delay in the signals coming from the SA node, AV node, or the Purkinje fibers. However, clinically the term heart block is used to refer to an AV block. This delays or completely stops communication between the atria and the ventricles. AV block is shown on the EKG as a delayed or prolonged PR interval. The P wave represents the activity in the at...

    In this universe there are many thing that we cannot explain. Among these many things is light. Light, as far as we know, come in different wavelengths and the size of the wavelength determine what type of light it is. The middle wavelength lights are what gives us the seven basic colors of red, orange, yellow, green, blue, indigo and violet. Beside these visible lights there are the lights that cannot be seen by the human eye. These invisible lights can be grouped into two other groups the lon...
  • Radio Waves Frequency Wave Audio

    Radio waves travel at 186, 000 miles per second through air. In contrast, sound waves travel at only 1/5 of a mile per second. If a modulation is made of the radio wave that exactly reproduces the amplitude and frequency characteristics of the original sound wave, then sound can be transmitted rapidly over long distances. This leads to a very interesting phenomena. During a live broadcast in New York, the music will reach listeners in California a fraction of a second before it can be heard by t...

    Resonance and Sound... Physics and Music Since sound is the medium of music, most of the physics of music is the physics of sound. It's important to remember that sound waves are compression waves. You can imitate a compression wave by stretching out a slinky (you do have a slinky, don't you? ) and flicking your finger against a coil at the end. Sound waves are not like the waves on the ocean or the waves you get by waving a stretched-out rope. Take a tuning fork (you do have a tuning fork, don...
  • Earthquakes Movement Of The Earth
    2,075 words
    EARTHQUAKE REFERENCE FILES Earthquake, shaking of the earth's surface caused by rapid movement of the earth's rocky outer layer. Earthquakes occur when energy stored within the earth, usually in the form of strain in rocks, suddenly releases. This energy is transmitted to the surface of the earth by earthquake waves. The study of earthquakes and the waves they create is called seismology. Scientists who study earthquakes are called seismologists. (Webster " sp. 423) The destruction an earthquak...

    Understanding Dreams Throughout history, humanity has tried to understand the meaning of dreams. Philosophers, mystics and scientists all cared about the issue. Though, they came to different answers. Ancient cultures and even modern ones have interpreted dreams as inspirations, divine signs and prophetic visions. They also interpret them as sexual fantasies, alternative realities, and many other beliefs fears and conjunctures. They " re so many interpretations, due to dreams' mysterious nature....

    Radio Waves In the modern society, radio is the most widely used medium of broadcasting and electronic communication: it plays a major role in many areas such as public safety, industrial manufacturing, processing, agriculture, transportation, entertainment, national defense, space travel, overseas communication, news reporting and weather forecasting. In radio broadcasts, they use the radio waves which can be both microwaves and longer radio waves. These are transmitted in two ways: amplitude m...

    EARTHQUAKES Objective: To define and discuss earthquakes and its effects. Earthquakes are a major catastrophe and can be a big threat to human lives. To understand earthquakes you must have a clear definition, know its mechanisms, be able to recognize the size and dynamics and understand its effects: I. Definition of Earthquakes. Earthquakes. Tsunamis. Landslides. Volcanoes II. Mechanisms. Faults b. Seismic Waves. Aftershocks III. Size. Strength. Classification of Seismic Waves 1. P (compress...

    Earthquakes have plagued our lives for as long as people have inhabited the earth. These dangerous acts of the earth have been the cause of many deaths in the past century. So what can be done about these violent eruptions that take place nearly with out warning Predicting an earthquake until now has almost been technologically impossible. With improvements in technology, lives have been saved and many more will. All that remains is to research what takes place before, during, and after an earth...

    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 soun...

    Tsunami A tsunami is a large water wave that is generated by seismic activity in or underlying layers known as faults. These enormous wave have historically affected many ways of life and still lie as a major factor for destruction in our coastal communities throughout the world. A tsunami is a wave chain or series of waves that is generated in a body of water by sea disturbance that vertically displaces the water. Earthquakes, landslides, volcanic activity and even cosmic materials can generate...

    An earthquake is one of the most terrifying phenomena that nature can dish up. We generally think of the ground we stand on as "rock-solid" and completely stable. An earthquake can shatter that perception instantly, and often with extreme violence. Up until relatively recently, scientists only had unsubstantiated guesses as to what actually caused earthquakes. Even today there is still a certain amount of mystery surrounding them, but scientists have a much clearer understanding. There has been...

    In this chapter we studied sound waves. In this paper you will read about how the ear works, how acoustics work and how sound waves are used in real life in medicine and music. Some basic characteristics of sound waves. Sound waves are detectable to the human ear when the range is within 20 to 20, 000 Hz. Sound waves are compressional waves also know as longitudinal waves. Sound waves require a medium to travel through. A medium is a substance or state of matter that the waves flow through. All...

    Sound is part of our everyday lives. Just like we have eyes for, we are given ears for hearing sound. We rarely take the time to think about the characteristics of sound and the ways that they are made. The basis for an understanding of sound and hearing is the physics of waves. Sound is a wave, which is created by vibrating objects and spread through a medium from one location to another. In this paper, we will look at the nature, properties and behaviors of sound waves. A wave can be describe...

    Introduction: There are many fascinating things about the universe and there are lots to learn from it too. Most of the discoveries in outer space were in our solar system and most of them were observed from the human eye aided by telescopes. Is it possible to observe objects from outer space using instruments other than the telescope? Fortunately, we are able to explore other parts of the electromagnetic spectrum using different kinds of observations such as the radio telescope, invented by Mr....
