mechanical waves need a medium to travel through, electromagnetic waves do not. Electromagnetic waves can travel through space, mechanical waves can not.

Is a sound wave mechanical or electromagnetic?
Seismic waves are mechanical waves.
What is the passage of an EM wave through a medium?
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.
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.
What type of em waves do cell phones depend on?
Cell Phones depend on The EM Radio Waves to Work. By: And
Do all EM waves transfer matter from place to place?
False. EM Waves do not transfer matter, they transfer energy.
How em waves different from mechanical waves?
Mechanical waves require a medium while Electromagnetic waves does not.
HOW are EM wave different from mechanical wave?
Mechanical waves require a medium while Electromagnetic waves does not.
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.
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.)
How are radio waves different from other waves on the EM spectrum?
They have different wavelength.
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.
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 is a electromagnetic wave different from a EM waves?
They're the same. EM stands for electromagnetic.
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
Is a sound wave mechanical or electromagnetic?
Seismic waves are mechanical waves.
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.
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.
