Katsushika Hokusai. The Great Wave off Kanagawa from Thirty-Six Views of Mount Fuji. c. 1831. Polychrome woodblock print on paper‚ 9 7/8” x 14 5/8” (25 x 37.1 cm). Hokusai’s The Great Wave off Kanagawa is a woodblock print that was published around 1831‚ and it is one of the most iconic Japanese works of art in the world. It depicts a colossal wave about to come crashing down on three fishing boats‚ or oshiokuri-bune—Japanese fishing boats that are known for their speed (Cartwright and Nakamura)

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

Main effects of sound pollution • Deafness‚ temporary or permanent‚ is one of the most prevalent effects of noise pollution. Mechanics‚ locomotive drivers‚ telephone operators etc all have their hearing impairment. • The first and foremost effect of noise is a decrease in the efficiency in working. Research has proved the fact that human efficiency increases with noise reduction. • Too much of noise disturbs the rhythms of working‚ thereby affecting the concentration required for doing a

What is the biggest animal ever to exist on Earth? By considerable measure‚ the largest known animal on Earth is the blue whale. Mature bluewhales can measure anywhere from 75 feet (23 m) to 100 feet (30.5 m) from head to tail‚ and can weigh as much as 150 tons (136 metric tons). That’s as long as an 8- to 10-story building and as heavy as about 112 adult male giraffes! These days‚ most adult blue whales are only 75 to 80 feet long; whalers hunted down most of the super giants. Female blue whales

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

Reflection On ‘The Korean Wave: The Seoul of Asia’ The main issue that was being discussed in this article is the effect of Korean wave for cultural influence on neighboring countries and how national identity impacts framing processes related to media coverage and public response. South Korea was known for its negative images such as the Korean wars‚ cycles of poverty and political instability. However‚ Korean wave has been successful in diminished the entire negative images due to trendy entertainers

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
