Wave

In the early part of the 19th century the scientific community was in the midst of a debate regarding the nature of light, specifically whether it was a particle or a wave. Isaac Newton argued that light behaved like a particle whilst a man by the name of Christian Huygens argued that light was in fact a wave. Unfortunately, as Newton was the president of the Royal Society at the time and many other scientists would simply take what he said to be the truth, this meant that few scientists of the…

A tsunami is a seismic sea wave. Displacement of water forms a sequence of waves and this generally happens in an ocean or a large lake.Tsunamis are different because normal waves are caused by wind or tides, which is actually generated by the gravitational pull of the Moon and Sun. According to Source 1, the first recorded tsunami was back in 7000-6000 BCE and this was in Portugal but the primary cause is unknown. Since then there have been many tsunamis that have caused damage, two of the…

Feminists and scholars have divided the feminist movement 's history into three "waves". The first wave refers mostly to the women 's suffrage movements of the nineteenth and early twentieth centuries. The second wave contains the ideas and actions associated with the women 's liberation movement beginning in the 1960s, campaigning for legal and social rights for women. The third wave consists of the reactions and results of the second wave’s ideas beginning in the 1990s. Although the terms…

between the two. We can perceive both light and sound. We see through eyes and hear through ears. Both light and sound are waves. Light is an electromagnetic wave whereas sound is a mechanical wave. Light is created by interaction of electric and magnetic field. It does not require any medium for propagation, so it can propagate in free space. On the other hand, sound wave requires physical medium, such as air, in order to sustain itself. For example, vibration of vocal chord creates cycles of…

iconic sound of ocean waves. The tribulations and trials of the main character, Anne, will leave the reader speechless at times. The novel becomes powerful with culture and history of that era as Montgomery creates a scenic picture for the reader with her use of details. Montgomery use of literary elements and details is similar to the sound of an ocean wave, because when one hears the calming or clashing sound, he or she can automatically picture a descriptive image of a wave in his or hers…

second, measured in Hertz. Amplitude is the height of the wave, and it is a measure of the amount of force applied over an area, expressed in Newton per square meter (N/m2). Amplitude is directly related to the acoustic energy or intensity of a sound, which is the amount of acoustic energy transmitted across unit area per second, expressed in Watts/surface area. Both amplitude and intensity are related to sound's power. Assuming a sound wave as an expanding sphere of energy, power is the total…

LIGO, the Laser Interferometer Gravitational-Wave Observatory, has been twenty-five years and more than half a billion dollars in the making. It involves 900 scientists and engineers, including many whose entire careers have been spent designing, building, and preparing to analyze data streaming in to LIGO. Their goal: To confirm, once and for all, Einstein’s century-old idea that gravity travels across space-time in the form of gravitational waves. Well, they did. This morning, the LIGO team…

see that Tristan messaged me and said "Get up! I'll be there in 5 minutes to pick you up! The waves are firing!", I instantly look towards the clock to see that I overslept. I immediately fling myself out of bed and rush into my still dark bathroom as I quickly brush my teeth and put my bathing suit on. I run over to the window to see if Tristan is here yet, but I can't focus on anything other than the waves crashing onto the shore of the white sandy beach only being barely lit up by the rising…

Do you know what a sonic boom is? Do you know how a sonic boom is created? After you read this paper you will be able to answer yes to both questions. A sonic boom is a thunder like sound that can only be heard on the ground. A sonic boom is a shock wave created by an airplane or another aerospace object flying equal to or greater than the speed of sound. A physicist named Ernst Mach established a way to measure airspeed to the speed of sound. (Wonderpolis pg.2). Mach 1 is when you are flying at…

for equal educational and economic opportunities, civil rights, and political presence. The feminist’s movement was divided in three waves. The first wave included the period of time from nineteenth century to the early twentieth. This period is mostly described by trying to get equal contract and property rights as their husbands. However, by the end of this wave the feminism activists shifted their focused and were primarily focusing on women gaining political power,…
