What is the difference between an electromagnetic wave and a mechanical wave?

Mechanical waves need a medium and em waves can travel through a vacuum


Why in infrared rays and ultraviolet rays are not visible to us what is the main point of difference between electromagnetic waves and mechanical waves?

The difference is in the different waves' frequency - therefore, the wavelength is also different. Our eyes are adapted to seeing specific frequencies; we can't see, or detect, just any type of EM wave. Mechanical waves are unrelated to EM waves, except that both are waves, and therefore share certain characteristics (having phenomena such as interference, polarization, etc.)


Can both electromagnetic waves and mechanical waves move throgh space?

Yes, but mechanical waves need matter to travel through. EM waves can travel through vacuums as well.


How are radio waves different from other waves on the EM spectrum?

They have different wavelength.


How can EM waves transfer energy differently in a material medium as compared to a vacuum?

when EM waves encounter a material medium, they can interact with it in much the same way that mechanical waves do. A mechanical wave transfer energy in two ways. As it travels, the wave moves potential energy from one place to another.


What waves have the most light waves?

Light wave is an electromagnetic wave, so light waves are a kind of wave. I don't understand what you mean by what waves have the most light waves. It's not possible to emit a combination of different kinds of waves (such mechanical, EM wave, sound wave) from a single source.


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.


How are electromagnetic wave and mechanical waves different?

The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.


How are mechanical and electromagnetic waves different?

mechanical waves need a medium to travel through and electromagnetic waves don't


What does mechanical wave needs to travel?

It has to travel through a medium. This is usually air, but could be any material such as water or steel. Mechanical waves cannot travel through vacuums as EM waves can x


How is a electromagnetic wave different from a EM waves?

They're the same. EM stands for electromagnetic.


How do the various kinds of em waves different from each other?

There are two main types of EM waves. Magnetic waves and Electronic waves. They exist at orthogonal relationships with M waves and E waves at 90 degrees to each other.

What distinguished electromagnetic waves from mechanical waves?

In a mechanical wave, some material is between stretched or moved from its ground, or normal, state. In an EM wave, a changing electrical field creates a changing magnetic field, which creates a changing E-field; and the process continues until these fields meet something that absorbs them. There is not material that is stretched or moved, the fields just operate on their own. EM waves operate quite well in the absence of any material whatsoever; mechanical waves need some media to propogate in.


How are electromagnetic and mechanical waves different?

The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.


Are there other waves besides electromagnetic and mechanical?

Quantifying the number of types of waves in fact reduces to the problem of quantifying the number of forces. In fact, mechanical waves are a subset of electromagnetic waves, so there are in fact three other types of waves on top of electromagnetic, for the three other fundamental forces: strong nuclear, weak nuclear, gravitational. Mechanical movement can be caused by any of the four fundamental forces. *Short answer: no. By the way, mechanical waves require a medium, where EM waves do not. They are the only, two, separate types of waves.


Are mechanical or electromagnetic waves more harmful?

There is a range to both of them. If you're in front of a tsunami or in an earthquake, mechanical waves are going to be your problem. If you're in outer space, the EM radiation of the sun is going to be your problem. Too much of anything will probably be harmful.


Is a radio wave a mechanical wave?

No, a radio wave is not a mechanical wave. A radio wave is a form of electromagnetic (EM) energy, and it does not require a medium through which to travel like a mechanical wave does. Radio waves can travel through the vacuum of space. Let's contrast that with a mechanical wave.A mechanical wave involves the transfer of mechanical energy into and through a medium. Sound waves (which travel through air) and water waves (which move through water) are mechanical waves. They cannot travel without a medium through which to move.


What is the energy transferred as em waves?

EM waves or electromagnetic waves is radiant energy.


What are the different types of EM waves?

The different types of EM waves known to man are (in the decreasing order of frequency or the increasing order of wavelength) : cosmic rays,gamma rays,x-rays,ultraviolet rays, visible light, infrared rays,microwaves, short radio waves and long radio waves.


What is the energy produced by EM waves?

EM waves produce radiation.


Is an electromagnetic wave a mechanical wave?

No. They are two different types of waves. Mechanical waves require a medium, such as air, to travel through. Electromagnetic waves do not need a medium to travel through.


What are 2 types of mechanical waves and how are they classified?

Mechanical waves are classified by how they move. 2 types of mechanical waves are transverse waves and longitudinal waves.


What does the e stand for in EM waves?

EM waves stand for Electromagnetic waves.


What are 3 examples of mechanical waves?

Three examples of mechanical waves are ocean waves, sound waves, and seismic waves. Mechanical waves can also be categorized as surface waves, longitudinal waves, and transverse waves.
