Mechanical waves require a medium while Electromagnetic waves does not.

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

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

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.)

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

They're the same. EM stands for electromagnetic.

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.

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.

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.

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

EM waves stand for Electromagnetic waves.

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.

EM waves or electromagnetic waves is radiant energy.

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.

EM waves produce radiation.

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.

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

Here are some differences between mechanical and electromagnetic waves.Mechanical waves can be either transverse or longitudinal. Electromagnetic waves are only transverse waves.Mechanical waves require a material medium to propagate. Thy can only travel in solids, liquids and gases. Electromagnetic waves do not require any medium. They can travel in vacuum also.Electromagnetic waves travel at the speed of light. Mechanical waves travel at much slower speeds.Mechanical waves propagate by the vibration of molecules of the medium. Electromagnetic waves travel by the oscillations of the electrical and magnetic vectors of a photon.

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.

EM waves are both Transverse and Longitudinal.

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.

Electromagnetic waves can travel through space or a medium while mechanical waves need matter to transfer energy.Apex- They don't require a medium to travel through.

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