If you pass a conductor through a magnetic field then an electric current will be produced in that conductor. An electric generator works in the same way except that there are many conductors, each producing a current, moving through a magnetic field. If you can make a device from a magnet that oscillates up and down in the waves, passing conductors through that magnetic field then that device will produce electricity. String a thousand of them across a tidal estuary and then you can produce a lot of electricity. Hope this helps.

presume you mean waves as in water and the sea. electric is produced when a magnetic field is moved at right angles to a conductor. any movement can be used to generate electric.

Existing wave power devices are categorized by the method used to capture the energy of the waves, by the intended location, and by the power take-off. Method types are wave power point absorber, occupying a small area; wave power attenuator, occupying a line parallel to wave propagation; and wave power terminator, occupying a line perpendicular to wave propagation. Locations are shoreline, offshore, and deep water. Types of power take-off include these: hydraulic ram, elastomeric hose pump, pump-to-shore, hydroelectric turbine, air turbine, and linear electrical generator.

Systems include oscillating water column, articulated pontoon, wave pump, anchored buoy, fixed buoy, and overtopping reservoir. Several of these designs incorporate parabolic reflectors as a means of increasing the wave energy at the point of capture.

These are descriptions of some wave power systems:

* A pontoon lying in the water is driven by wave action to push or pull an electrical generator. (See Pelamis Wave Energy Converter.)
* Wave action compresses air in a tunnel which drives the vanes of a generator.
* A device called CETO, currently being tested off Fremantle, Western Australia, has a seafloor pressure transducer coupled to a high-pressure hydraulic pump, which pumps water to shore for driving hydraulic generators or running reverse osmosis desalination.
* Waves overtop the side of a reservoir, and the water in the reservoir runs hydroelectric generators. (See Wave Dragon wave energy converter.
The fundamental challenges of wave power are:
- efficiently converting wave motion into electricity... generally speaking, wave power is available in low-speed, high forces and motion is not in a single direction. Most readily-available electric generators like to operate at higher speeds, with lower input forces, and they prefer to rotate in a single direction.
- constructing devices that can survive storm damage and saltwater corrosion. Likely sources of failure include seized bearings, broken welds, and snapped mooring lines. Knowing this, designers may create prototypes that are so overbuilt that materials costs prohibit affordable production.
- low total cost of electricity... wave power will only be competitive when total cost of generation (p/kWhr) is reduced. The winning team will be the one that develops the lowest-cost system (which includes the primary converter, power takeoff system, mooring system, installation & maintenance procedures.... )

Just like anything else that moves can make electricity,if the energy the movement creates is harnessed.

There are many technologies available to convert energy from wave into electricity. One of them is "SEA SNAKE". You can check it out here: http://www.discover.com/issues/dec-05/features/ocean-energy/

What type of waves? There are many types of waves, including water waves, and salutes! Be specific... Your question is meaningless as it now stands.
