another name for pressure wave is a P-wave EDIT: Another name for P-waves or Pressure waves are Compressional, Longitudinal, P, Dilation waves. The particle motion is in the direction of wave propagation These waves occur in Solids, Liquids, and Gases whereas Shear, transverse, S, or equivoluminal waves only occur in solids.
S waves, or secondary waves, are transverse seismic waves, meaning that the particles being effected by the wave are moving perpendicular to the wave's propagation.
The wave are classified as their motion respect to their propagation.
No.
Particles move back and forth in the same direction as the waves due to the energy transfer from the wave to the medium's particles. In longitudinal waves, such as sound waves, compressions and rarefactions cause particles to oscillate along the direction of the wave's propagation. This movement occurs as particles collide and exert forces on one another, allowing the wave energy to travel through the medium while the particles themselves mainly return to their original positions.
Mechanical waves require a medium for their propagation whereas electromagnetic waves require a medium for their propagation.
Rock.
Electromagnetic waves, such as light and radio waves, do not require a material medium for their propagation. They can travel through a vacuum because they are created by oscillating electric and magnetic fields. This is in contrast to mechanical waves, like sound waves, which require a medium such as air or water to propagate.
A Sound wave, water wave, earth quake wave. Electromagnetic waves (radio, light, etc.) do not require a medium for propagation.
The propagation of light waves in a vacuum is the movement of light waves through empty space. In physics, propagation refers to the transmission or spread of waves or energy through a medium. In this context, the propagation of light waves in a vacuum demonstrates the fundamental concept of how waves can travel through space without the need for a material medium.
Mechanical waves
The Earth itself is.
Sound waves: These are mechanical waves that require a medium (such as air, water, or a solid material) for propagation. Water waves: Also known as surface waves, they are a type of mechanical wave that travels through a medium (such as water). Seismic waves: These are waves that are generated by earthquakes and require a medium, such as the Earth's crust and mantle, for propagation.
Propagation of disturbance suffered by a particle in a medium is called wave propagation Wave Propagation is a term used to estimate the actions and characteristics of a wave of motion either in solids, liquids, gasses, or electrical radio type waves by the environment it is in and what factors affect those waves behaviors.
In a way, they don't. There is always a medium; though for some waves, this medium can be empty space.
Electromagnetic waves (like light) don't require a medium for propagation, unlike mechanic waves (like sound).
For transverse waves, the vibration of the medium is perpendicular to the direction of the wave propagation. For longitudinal waves, the vibration of the medium is parallel to the direction of the wave propagation.
