How are waves generated and what do they do?
In fluid dynamics, wind waves, or wind-generated waves, are surface waves that occur on the free surface of bodies of water (like oceans, seas, lakes, rivers, canals, puddles or ponds). They result from the wind blowing over an area of fluid surface.

What does a wave do?
In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.

What is the best definition of a wave?
wave. In physics, any regularly recurring event, such as surf coming in toward a beach, that can be thought of as a disturbance moving through a medium. Waves are characterized by wavelength, frequency, and the speed at which they move.

What are the different types of waves?
There are three categories:
- Longitudinal wave *s - Movement of the particles are parallel to the motion of the energy.
- Transverse wave *s - movement of the particles are at right angles (perpendicular) to the motion of the energy.
- Surface wave *s - particles travel in a circular motion.

What is carried by a wave?
Light, heat, radio, and similar types of energy are carried by a variety of waves in the ELECTROMAGNETIC SPECTRUM. Some energy waves need a medium, such as water or air, through which to travel. The medium moves back and forth as waves carry energy through it, but it does not actually travel along with the wave.
5
How do we use waves to generate electricity?
When wind blows across the sea surface, it transfers the energy to the waves. They are powerful source of energy. The energy output is measured by wave speed, wave height, wavelength and water density. The captured energy can then be used for electricity generation, powering plants or pumping of water.
6
How is energy transferred by a wave?
Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance. It is the disturbance that travels in a wave, transferring energy.
7
What causes waves to be bigger than others?
According to the Encyclopedia of the Sea, a wave is "the oscillations of the sea caused by the wind blowing along the surface and moving in the direction in which the wind blows." On the West Coast, the prevailing winds are behind the waves, which increases the waves' energy.
8
Which planet causes waves?
Tides are actually waves, the biggest waves on the planet, and they cause the sea to rise and fall along the shore around the world. Tides exist thanks to the gravitational pull of the moon and the sun, but vary depending on where the moon and sun are in relation to the ocean as the earth rotates on its axis.

How do electromagnetic waves work?
These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
10
Where do the waves get their energy from?
Answer and Explanation: Ocean waves get their energy mainly from the winds that blow across their surface. As the winds blow, friction builds up and causes the water to be pulled along, forming a crest.
11
What are the different parts of a wave?
A crest (or peak) of a wave is one of the top-most parts, as high as the wave goes. A trough is the lowest part, as low as the wave goes. The amplitude of a wave is the vertical distance between the center line and a peak, or the center line and a trough. This should normally be exactly the same distance.
12
What is a tidal wave and what causes it?
A tidal wave is a regularly reoccurring shallow water wave caused by effects of the gravitational interactions between the Sun, Moon, and Earth on the ocean. The term "tidal wave" is often used to refer to tsunamis; however, this reference is incorrect as tsunamis have nothing to do with tides.
13
How is a tidal wave created?
Normal ocean waves are caused by wind and start out as ripples on the surface of the ocean. Tsunamis on the other hand, are usually caused by a seismic disturbance at the bottom of the ocean, such as an earthquake, landslide or volcanic eruption, or sometimes by meteors or asteroids slamming into the Earth.
14
Are tsunamis shallow water waves?
Tides and tsunamis are shallow-water waves, even in the deep ocean. The deep ocean is shallow with respect to a wave with a wavelength longer than twice the ocean's depth.
15
How do waves work with the moon?
Winds and currents move the surface water causing waves. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the Earth is also being pulled toward the moon (and away from the water on the far side).
16
What are waves in your hair?
Waves are a hairstyle for afro-textured hair in which the curls are brushed and flattened out, creating a ripple-like pattern. The hairstyle begins with a short-cropped haircut and frequent brushing of the curls, which trains the curls to flatten out.
17
What is the cause of a tsunami?
A tsunami is a series of large waves generated by an abrupt movement on the ocean floor that can result from an earthquake, an underwater landslide, a volcanic eruption or - very rarely - a large meteorite strike. However, powerful undersea earthquakes are responsible for most tsunamis.
18
What is high tide and low tide?
The following diagram shows how the moon causes tides on Earth: In this diagram, you can see that the moon's gravitational force pulls on water in the oceans so that there are "bulges" in the ocean on both sides of the planet. The moon pulls water toward it, and this causes the bulge toward the moon.
19
How does each thing causes a wave?
The wind makes waves as it blows across the surface of the ocean. Most of the surface waves we see on the ocean are caused by wind. When winds blow across the ocean, some of the energy of the wind is passed to the water. Each particle of water in a wave moves in a circle.
