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

Longitudinal and transverse waves Sound is transmitted through gases‚ plasma‚ and liquids as longitudinal waves‚ also called compression waves. Through solids‚ however‚ it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure‚ causing local regions of compression and rarefaction‚ while transverse waves are waves of alternating shear stress at right angle to the direction of propagation

The book The Wave by Morton Rhue is a fiction story but is based on an incident that occurred in a high school in Palo Alto‚ California. In the book‚ history teacher Ben Ross shows a movie to his high school class about Germany while studying World War Two. After a series of questions after the movie‚ Ross conducts an experiment to roughly explain the cruel behavior of the German Nazis during the Holocaust. He starts an organization called the Wave in his class that spreads rapidly throughout the

What are UltraSonic Waves? Ultrasonic waves are sound waves with frequencies high about human hearing and short wave lengths. Sound waves have frequencies about 20‚000 to 100‚000. Also Ultrasound frequencies range from 20 kHz (the upper range of hearing for a young adult human) through 150 kHz (audible to some bats and other creatures)‚ right up to 10 MHz (used in some medical treatments and industrial cleaning applications). While these frequencies overlap with those of radio waves‚ they are different

quotes). The Fifth Wave by Rick Yancey is about an alien attack on Earth and each attack is called a wave. Each wave kills more people than the last. During the fourth wave a teenager named Cassie gets separated from her little brother Sam. Cassie does everything in her power to reunite with her brother. During her search‚ fate leads her to meet a mysterious character named Evan Walker. Cassie is forced to trust Evan if she wanted any chance of finding her brother. The Fifth Wave uses alternating

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

explaining in turn what light and sound are‚ but first we need to know what waves are in order to make it easy to understand the others. Waves exist in both sound and light. Or to make a better sense‚ it is what makes them exist. Waves are vibrations that transfer energy from place to place within a medium. The medium could be solid‚ liquid or gas. It is the medium that vibrates as the waves travel through. There are some waves that don’t need to travel through a substance. They may be able to travel

The first wave of feminism arose in the nineteenth and early twentieth century.The first wave mainly focused on women’s legal issues especially women’s right to vote. The feminists fighting for the right to vote were mostly made up of two groups‚ the Suffragettes and the Suffragists. The suffragists were quite peaceful in their methods of recognition for women in contrast to the suffragettes who were quite violent‚ radical in their ways created some bad publicity for feminists and in part created
