Why do EM waves not need a medium?
As I understand it, electromagnetic waves have two components which are the result of each other, i.e., when a moving electric charge creates a changing magnetic field at point X then a changing electric field is created at point Y and this repeating process is what creates EM waves, so therefore, it requires no medium …
Which waves require a medium for transmission?
Sound and water waves are mechanical waves; meaning, they require a medium to travel through. The medium may be a solid, a liquid, or a gas, and the speed of the wave depends on the material properties of the medium through which it is traveling.
Which waves require a material medium for transmission quizlet?
0.5 hertz. Which waves require a material medium for transmission? (c) Sound waves require a material medium for transmission, since sound waves are a mechanical wave.
Why do mechanical waves need a medium?
Mechanical waves are waves that require a medium in order to transport their energy from one location to another. Because mechanical waves rely on particle interaction in order to transport their energy, they cannot travel through regions of space that are void of particles.
Do seismic waves require a medium?
Common types of mechanical waves include sound or acoustic waves, ocean waves, and earthquake or seismic waves. In order for compressional waves to propagate, there must be a medium, i.e. matter must exist in the intervening space.
What type of wave does not need a medium to travel?
Electromagnetic waves
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
What types of waves require a medium?
Waves which require any medium for their propagation are called mechanical waves. For example: Water waves, sound waves, and waves produced on the string and spring. Earthquakes produce seismic waves.
What waves need a medium to travel?
At mechanical waves need a medium to travel in order to transport their energy from one location to another. Mechanical waves require a medium to travel through so that they can transmit energy. Some examples of mechanical waves are water waves, sound waves and the waves of a slinky or jump rope.
Do electromagnetic waves require mediums?
Electromagnetic waves do not require a medium in order to transport their energy. Mechanical waves are waves that require a medium in order to transport their energy from one location to another. Sound is a mechanical wave and cannot travel through a vacuum.
What do mechanical waves require to travel?
The mechanical waves need a medium like water, air, or anything for it to travel. The ripples made in a pool of water after a stone is thrown in the middle are an example of mechanical waves.
