What is the medium of wave propagation?
Examples of materials that are used to produce or serve as propagation media are (a) metals for electric current signals, (b) glass and other dielectric materials for lightwave signals, and (c) air for sound wave signals, with the exception that a vacuum or free space is considered as a propagation medium for …
How do you determine wave propagation?
directions of propagation. To find the direction of propagation of an E&M wave, point the fingers of the right hand in the direction of the electric field, curl them toward the direction of the magnetic field, and your thumb will point in the direction of propagation.
What is the law of wave propagation?
The fundamental laws of wave propagation at an interface, the laws of reflection, refraction, and diffraction are arrived at from a consideration of wave scattering from an array of scattering centers. An exact equation for the summation of the phases and amplitudes of scattered waves arriving at a point is developed.
What are seismic waves types?
There are three basic types of seismic waves – P-waves, S-waves and surface waves. P-waves and S-waves are sometimes collectively called body waves.
What are the two types of wave based on the medium in which they propagate How do they differ?
Physical waves require matter through which to propagate. Physical waves are further distinguished by the phases of matter through which they can move. Longitudinal waves can pass through liquids and gasses while transverse waves require a material to be solid to propagate.
What is a medium in Science waves?
A medium is a substance or material that can carry a wave. The wave medium is not the wave and it does not make the wave; it merely carries or transports the wave from its source to other locations. Subsequently, the disturbance travels through the medium such as ocean water, violin strings, spring toys, air, etc.
How are P waves propagated They are propagated through?
In P or compressional waves, the vibration of the rock is in the direction of propagation. P waves travel fastest and are the first to arrive from the earthquake. The PP (one bounce) and PPP (two bounces) waves travel more slowly than the direct P because they pass through shallower, lower velocity rocks.
