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. The medium through which a mechanical wave moves through can be a fluid, solid or...
The medium of a wave is any substance that carries the wave, or through which the wave travels. Ocean waves are carried by water, sound waves are carried by air, and the seismic waves of an earthquake are carried by rock and soil.
Waves travel by transferring energy from particle to particle through a medium such as air or water. In some cases, this energy transfer creates a motion perpendicular to the direction of travel, creating transverse waves. Other waves travel by compressing the medium an...
Sound travels as a back-and-forth vibration of the particles of its medium. It is a longitudinal mechanical pressure wave that varies greatly in its speed of travel and the distance it remains coherent, dependent upon the medium. Sound in air travels relatively slowly a...
Waves can travel through matter called a medium. This is true for mechanical waves that include sound, water and slinky waves. However, this is not the case for electromagnetic waves, which can travel through a vacuum.
Electromagnetic waves do not require a medium to be transmitted. These waves, which freely travel through different types of materials, are produced due to the combined effects of a magnetic field and an electric field.
Light waves travel through the process of electromagnetic radiation. The combination of electrical and magnetic fields that light has is what gives light the distinct quality of being able to travel with or without a medium, which is unlike other wave forms.
