On the fateful day in 1896 when the great waves approached Japan, fishermen at sea noticed no unusual swells.

Now as you step inside, instead of seeing particles orbiting around like planets, you see waves and ripples very much like the ripples that you get on the surface of a pond when you drop a stone into it.

The wind bored a hole between his shoulder blades, and when he looked at the choppy waves coming and going and crossing each other he could see his head down there, bleeding, wedged between the rocks and the waves.

* A Natural arch is formed when a sea stacks is eroded through by waves.

The periodic arrays of submicrometre spherical particles provide similar arrays of interstitial voids, which act as a natural diffraction grating for visible light waves, particularly when the interstitial spacing is of the same order of magnitude as the incident lightwave.

Similar effects occur when light waves travel through a medium with a varying refractive index or a sound wave through one with varying acoustic impedance.

Sound waves can diffract around objects, which is why one can still hear someone calling even when hiding behind a tree.

It is a result of the superpostion of many waves with different phases, which are produced when a laser beam illuminates a rough surface.

It is similar to what occurs when waves are scattered from a diffraction grating.

When the two waves are in phase, i. e. the path difference is equal to an integral number of wavelengths, the summed amplitude, and therefore the summed intensity is maximum, and when they are in anti-phase, i. e. the path difference is equal to half a wavelength, one and a half wavelengths, etc., then the two waves cancel and the summed intensity is zero.

For low-frequency radiation ( radio waves to visible light ) the best-understood effects are those due to radiation power alone, acting through the effect of simple heating when the radiation is absorbed by the cell.

An early example is in Maurice Tourneur's The Pride of the Clan ( 1917 ), in which there is a series of shots of waves beating on a rocky shore which are shown when the locale of the story, which is about the harsh lives of fisher folk, is being introduced.

The absence of a similar precaution in construction of his Mosè in Egitto led to disaster in the scene depicting the passage of the Israelites through the Red Sea, when the defects in stage contrivance always raised a laugh, so that the composer was at length compelled to introduce the chorus " Dal tuo stellato soglio " to divert attention from the dividing waves.

The red dot overtakes two green dots when moving from the left to the right of the figure. New waves seem to emerge at the back of a wave group, grow in amplitude until they are at the center of the group, and vanish at the wave group front. For surface gravity waves, the water particle velocities are much smaller than the phase velocity, in most cases.

Native Celtic peoples had been marginalized during the period of Roman Britain, and when the Romans abandoned the British Isles during the 400s, waves of Germanic peoples, known to later historians as the Anglo-Saxons, migrated to southern Britain and established a series of petty kingdoms in what would eventually develop into the Kingdom of England by AD 927.

The principle of superposition of waves states that when two or more waves are incident on the same point, the total displacement at that point is equal to the vector sum of the displacements of the individual waves.

The strangely small ripples on the photo fit the size and circular pattern of small ripples as opposed to large waves when photographed up close.

So, an aircraft traveling at Mach 1 at 20 ° C or 68 ° F, at sea level, will experience shock waves in much the same manner as when it is traveling at Mach 1 at 11, 000 m ( 36, 000 ft ) at-50 ° C or-58F, even though it is traveling at only 86 % of its speed at higher temperature like 20 ° C or 68 ° F.

* Typically some sound is audible at any given moment, when the vibration of these sound waves reaches the ear drum it moves in response and allows the sense of hearing.

As I dug in behind one of the bales we were using as protection, I grudgingly found myself agreeing with Oso's logic, especially when I imagined what would have happened to Missy if Old Knife's large party of screeching warriors had overrun our company.

McBride gave him his opportunity when he showed up in town with a pistol on his hip.

His face was stiff with anger when they let go of his arms.

They'd peddled the soap virtually alone, and without much success, until about a year ago, when -- with the addition of `` SX-21 '' to their secret formula and the inauguration of a high-powered advertising campaign -- sales had soared practically into orbit.

I was loaded with suds when I ran away, and I haven't had a chance to wash it off.

And, as a matter of fact, Nicolas had slept in the park only part of one night, when he discovered that Munich's early mornings even in summer are laden with dew.

He used the blanket for late morning naps when hosts of the night had gone off to jobs and proved reluctant to leave him in their small rooms with their few possessions.

As she was rather tired this evening, her simple `` Thank you for the use of your bath '' -- when she sat down opposite him -- spoken in a low voice, came across with coolnesses of intelligence and control.

All the drivers knew about the plates and they also knew about the big floppy straw hat with shredded edges, the kind natives in travel ads wear when they are out joyfully chopping cane.

Wild boar watched their progress with little pig eyes, and grunted derision when they didn't consider such game worthy of a shot from the.

when he went home at night, he took her with him in his mind, and she did the things the anonymous Woman used to do, and he did the thing afterwards each time as he used to do.

That night he dreamed a dream violent with passion, in which he and the Woman, now the teacher, did everything except engage in the act ( and this probably only because he had never engaged in the act in reality ), and when he awoke the next morning his heart was afire.

He said, lapsing into the profanity he often used when away from his parents and especially when he was with Charles.

Shy, actually, he avoided feminine overtures and seemed truly ignorant of the girls' desires when they sought to make liaisons with him in the open fields, in carriages and in boathouses.

In fact it has caused us to give serious thought to moving our residence south, because it is not easy for the most objective Southerner to sit calmly by when his host is telling a roomful of people that the only way to deal with Southerners who oppose integration is to send in troops and shoot the bastards down.

In 1961 the first important legislative victory of the Kennedy Administration came when the principle of national responsibility for local economic distress won out over a `` state's-responsibility '' proposal -- provision was made for payment for unemployment relief by nation-wide taxation rather than by a levy only on those states afflicted with manpower surplus.

On Fridays, the day when many Persians relax with poetry, talk, and a samovar, people do not, it is true, stream into Chehel Sotun -- a pavilion and garden built by Shah Abbas 2, in the seventeenth century -- but they do retire into hundreds of pavilions throughout the city and up the river valley, which are smaller, more humble copies of the former.

His collaboration with Washington, begun when he was the general's aide during the Revolution, was resumed when he entered the first Cabinet as Secretary of the Treasury.

But the fences were still in place fifty-odd years ago, and when we stood on the gate to look over, the sidewalk under our eyes was not cement but two rows of paving stones with grass between and on both sides.

When words can be used in a more fresh and primitive way so that they strike with the force of sights and sounds, when tones of sound and colors of paint and the carven shape all strike the sensibilities with an undeniable force of data in and of themselves, compelling the observer into an attitude of attention, all this imitates the way experience itself in its deepest character strikes upon the door of consciousness and clamors for entrance.

But he plunges into yet another, this time with Norway, and is killed in an assault on the fortress of Fredrikshall, being only thirty-six years of age when he died.

Here there may be an analogy with cancer: we can detect cancers by their rapidly accelerating growth, determinable only when related to the more normal rate of healthy growth.
