Both mechanical waves and EM waves interact with a change in what?
All waves move energy, not matter. All waves are created by vibrations. Mechanical waves are caused by vibrating matter such as vocal chords or a drum. EM waves are created by vibrating electrons in atoms that propogate through the electric and magnetic fields that exist everywhere in the universe. All waves can reflect, refract. and diffract. This is where the similarities end. Both types of waves interact with matter and experience a change in velocity but do not interact with each other. Mechanical waves require matter as a medium through which to travel, they don't travel through a vacum. EM waves travel best through a vacum and lose energy as they move into more dense matter. All waves refract when they change velocity as they move from one medium into another, like air into water. Remember, there are some similarities amongst all types of waves, EM, mechanical, surface, and siesmic, but their behaviors are quite varied and complex.
What are the good and bad things about wave power?
Good: Wave power is renewable and environmentally friendly, producing clean energy without greenhouse gas emissions. It also has the potential to provide a consistent source of energy as waves are a steady and predictable resource.
Bad: The technology for harnessing wave power is still relatively expensive and can be disruptive to marine ecosystems. Additionally, the energy output can be variable depending on weather conditions, which may impact its reliability as a primary energy source.
Pros of biomass is that it's renewable, made locally with minimal cost, promotes energy independence and converts waste into fuel. Cons of biomass is that large areas of land are needed, the geography of a country will limit the type of biomass used to create energy and some materials are not available year round.

dis advantages
· Disturbance or destruction of marine life (including changes in the distribution and types of marine life near the shore)
· Possible threat to navigation from collisions due to the low profile of the wave energy devices above the water, making them undetectable either by direct sighting or by radar. Also possible is the interference of mooring and anchorage lines with commercial and sport-fishing.
· Degradation of scenic ocean front views from wave energy devices located near or on the shore, and from onshore overhead electric transmission lines

What property of a wave increase as the wave energy increase?
An increase in energy corresponds to an increase in frequency or a decrease in wavelength.
How could you increase the power of a wave in a spring?
To increase the power of a wave in a spring, you can increase the amplitude or frequency of the wave. This can be done by adjusting the force applied to the spring or changing the mass attached to it. Additionally, ensuring that the wave is perfectly synchronized with the natural frequency of the spring can help maximize its power.
What is the main advantage of using alternating current in the power grid?
Low loss transmission of power at high voltages for long distances then the ability to transform down to lower voltages near the point of usage, i.e. substations and pole transformers near residences.
Is wave energy always available?
Wave energy is not always available as it is dependent on the presence of waves. Factors such as weather conditions and location play a role in the consistent availability of wave energy. However, in areas with consistent wave patterns, wave energy can be a reliable source of renewable energy.
Which is the appropiate unit to measure the width of a textbook?
appropriate unit to measure the width of a textbook = ce
ntimeters
What are features produced by wave action?
Wave action can produce features such as beaches, sandbars, ripples, and wave-cut cliffs along coastlines. It can also lead to the formation of sea stacks, caves, and arches through erosion and deposition processes.
Why don't all countries use wave power?
There are a number of reasons why no country actually uses much wave power at the moment.
The technology is still not fully worked out.
Experimental stations do generate power, but not in significant amounts.
Why do waves expend so much energy on a rocky headland?
When waves approach a rocky headland, they are forced to change direction and refract around the obstacles. This change in direction causes an increase in wave energy and pressure on the headland, resulting in erosion and the release of energy as the waves crash against the rocks. The energy is dissipated as the waves break, causing erosion and shaping the coastline over time.
What are the top countries using wave energy?
i only know three they are scotland, portugaland australia.
How is the wave power produced?
Wave power is produced by capturing the energy from ocean waves and converting it into electricity. This is typically done using devices such as wave energy converters that harness the kinetic and potential energy of the waves to generate power. The movement of the waves drives the turbines, which in turn generate electricity.
How do you use the word national in a sentence?
A sentence with the word national in it could include:
"I made it to the national spelling bee!"
or, here is a twist on it:
"I am part of the United States nation."
Hope this helps, please give trust point? Thanks :)
How are the mechanical waves formed?
Any kind of disturbance triggers mechanical waves that propagate perpendicular to the motion of disturbance.
However for mechanical motion, it is necessary that the wave is propagated in a medium.
Waves are caused by the wind blowing over the surface of the ocean. In many areas of the world, the wind blows with enough consistency and force to provide continuous waves. There is tremendous energy in the ocean waves. Wave power devicesextract energy directly from the surface motion of ocean waves or from pressure fluctuations below the surface.
Wave power varies considerably in different parts of the world, and wave energy can't be harnessed effectively everywhere. Wave-power rich areas of the world include the western coasts of Scotland, northern Canada, southern Africa, Australia, and the northwestern coasts of the United States.
Ocean Wave Energy TechnologiesA variety of technologies have been proposed to capture the energy from waves. Some of the more promising designs are undergoing demonstration testing at commercial scales.
Wave technologies have been designed to be installed in nearshore, offshore, and far offshorelocations. The OCS Alternative Energy Programmatic EIS is concerned primarily with offshore and far offshore wave technologies. Offshore systems are situated in deep water, typically of more than 40 meters (131 feet).
While all wave energy technologies are intended to be installed at or near the water's surface, they differ in their orientation to the waves with which they are interacting and in the manner in which they convert the energy of the waves into other energy forms, usually electricity. The following wave technologies have been the target of recent development.
Terminator devices extend perpendicular to the direction of wave travel and capture or reflect the power of the wave. These devices are typically onshore or nearshore; however, floating versions have been designed for offshore applications. The oscillating water column is a form of terminator in which water enters through a subsurface opening into a chamber with air trapped above it. The wave action causes the captured water column to move up and down like a piston to force the air though an opening connected to a turbine.
A point absorber is a floating structure with components that move relative to each other due to wave action (e.g., a floating buoy inside a fixed cylinder). The relative motion is used to drive electromechanical or hydraulic energy converters.
This type of wave is most dangerous?
Tsunamis are generally considered the most dangerous type of wave due to their large size and destructive power, which can cause widespread devastation when they reach land.
How much energy does wave power provide?
Wave power has the potential to provide a significant amount of energy, with estimates suggesting that it could potentially generate up to 10% of the world's electricity. However, the actual amount of energy harnessed from wave power can vary depending on factors such as the location of the wave energy device and the intensity of the waves.
