Electromagnetic Waves It was once the great Scottish physicist James Clerk Maxwell (1831-1879) who had presented that electric and magnetic fields unstable together can form a spreading wave‚ appropriately called an electromagnetic wave. The properties of an electromagnetic wave are as follows: 1. They can travel through a vacuum at the same high speed‚ which is much faster than other types of waves that travel through a material. 2. They show the normal wave properties of reflection‚ refraction

Characteristics and Nature of Waves In physics‚ a wave is a disturbance that travels through space and time‚ usually accompanied by the transfer of energy. Waves travel and the wave motion transfers energy from one point to another‚ often with no permanent displacement of the particles of the medium—that is‚ with little or no associated mass transport. They consist‚ instead‚ of oscillations or vibrations around almost fixed locations. For example‚ a cork on rippling water will bob up and down

Beginning in the summer of 1869 Gustave Courbet produced a series of paintings depicting stormy seas during his stay at Etretat on the Normandy coast. The Wave (La Vague c.1872) exhibited in the National Gallery of Victoria is one such painting that features the central motif of a cresting wave. While many viewed the work as a simple realist seascape‚ the political implication of the work suggested by some of Courbet’s contemporaries is hardly discernable to the modern viewer. It can only be understood

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 that is submerged at high tide and exposed at low tide‚ the intertidal zone ‚ is an

Physiotherapist - What Do They Do? Physiotherapy is generally thought to be a non-intrusive treatment that uses different activities and back rub systems to urge the body to mend itself. It is likewise used to restore patients so they can learn muscle developments once more‚ or to get over a throbbing painfulness connected with recuperating wounds after a mischance. Much of the time working out‚ controlling and kneading the body all falls inside of the domain of physiotherapy and are instruments

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

INFRARED WAVES * Infrared (IR) light is electromagnetic radiation with a wavelength longer than that of visible light How They’re Made: Infra red waves are just below visible red light in the electromagnetic spectrum ("Infra" means "below"). You probably think of Infra-red waves as heat‚ because they’re given off by hot objects‚ and you can feel them as warmth on your skin. Infra Red waves are also given off by stars‚ lamps‚ flames and anything else that’s warm - including you. The detector

Water Waves By Anna Introduction Water waves have been around for years; learning about water waves can help you understand the outside world. Water waves can be used in many ways‚ but they can also be harmful‚ too. When were they discovered? Water waves have been around since the creation of the earth‚ but Isaac Newton came up with a theory; after studying waves in about 1687. What is the biggest wave? In 1958 the biggest tsunami wave was recorded. How much harm can water waves really
