What is the medium propagation of earhquake waves?

The Earth itself is.


Medium for the wave?

The medium of any wave is the material that the wave energy travels through; in this case water.


What is the medium of wave propagation?

The "medium" for a wave is whatever the wave goes through - or more precisely, whatever it needs, in order to propagate. In this case, the Earth.


What wave that need a medium in order to propagate?

All sound waves, be that ultrasound or audible sound. Likewise water waves...


How are sound waves and eletromagnetic waves different?

Sound waves require a medium such as air, solid, or liquid in order to propagate. Electromagnetic waves do not require a medium for propagation and can move through a vacuum.


What is one place sound waves cannot travel?

Sound waves cannot travel in space. Sound waves some medium in order to propagate.


Is there sound in a vacuum?

No, you can not produce sound in a vacuum. Sound wave needs medium (for example air) to travel unlike electromagnetic wave which can travel through empty space.actually, sound wave does not propagate itself rather it needs a medium by which sound particle can transfer there energy from one place to other, so it seems like moving. for eg. when u throw a stone in water ,some ripples form in water they seems to moving but not. like this sound propagate. hence it requires medium


What is propagate?

To propagate is to increase and spread by means of reproduction.


What is needed for a plant to germinate?

The Answer: A plant needs water in order to spread its type. A seed also needs air and a growing medium such as soil in order to germinate.


What is the speed of sound waves when travelling through a vacuum?

The speed of sound in vacuum is zero. Sound needs a material medium in order topropagate. Since vacuum contains no material medium, sound does not propagate.Therefore, it never moves from the source of the sound, and theSpeed = (distance covered in any time interval) divided by (time to cover the distance)is zero.


What does a wave need to move?

A wave, by definition, is an oscillation propagating through a medium. So in order for a wave to move it needs a medium (ie. air, water, earth, etc.) and energy. In the case of light (ie. photons), which is a form of wave that can travel through a vacuum, the medium is the electromagnetic field.


What is the medium for light?

Light, whatever the wavelength, does not need a medium in order to radiate.
