How do waves behave,?

Answer 1

Depending whether they are sound (longitudinal) or light (transverse).

Longitudinal waves need a medium to travel through i.e. Air, as they are basically vibrations transmitted through the air molecules (as they hit each other and carry the energy.)

Light waves are different, they have both a magnetic and electric component (called an EM wave), which are perpendicular to each other and also perpendicular to the wave direction.

Waves can be refracted (like light through a prism) where white light can be split into its component colours (as each colour is refracted a different amount.)
EM Waves do not need media to travel through - they can travel in a vacuum (i.e. space)

EM Waves always travel at the speed of light in a vacuum - they slow down when they travel through water and glass etc..

Sound waves travel faster in solids and liquids (as the particles are closer together.)

Answer 2

Waves are a delight and a devilment: the roller-coaster thrill of a wild surf; the misery of a cold water trickle down the neck, the satisfaction of a well steered course to windward; the agony of seasickness on the lee rail.

Imagine sailing without waves. A glassy smooth surface unbroken even by our own wake. Pleasant perhaps, but boring. What sense of speed would we have without our breaking bow wave as we crank along at a neck-snapping six or seven knots? It is largely the skill of getting on or around waves that separates the winners from the losers in our sport. A better understanding of their nature can only help to improving our sailing ability or at least our ability to sound more knowledgeable at the yacht club bar.

Even a careful observer of the confused and undisciplined surface of the ocean may find it difficult to believe that waves are controlled by natural laws, but they are. We all know something about the natural laws of waves without having thought much about it.

Long waves (crests far apart) travel faster than short waves (crests close together).
Very long waves called swell come from storms far away but are too long and round to be dangerous to small boats until they reach shallow water.
Waves generated by the wind locally are steeper and shorter; and the stronger and longer the wind blows the bigger and longer the waves get.
The key to further understanding is to look at the sea state as a collection of many simple component waves, all of different sizes and lengths, all running in different directions, and all piled on top of one another.

Answer 3

hi
depend of the majore that effect of it
it behave as you want , you can controle it
for example you can controle the wave of radio or tv or any wave

thanks
