Understanding S-Wave and P-Wave Annihilation - Physics Forums
2005年8月17日 · s-wave and p-wave refer to the orbital angular momentum of the initial state. The notation is related to early spectroscopic notation, with the connection: Spectral line type s wave L=0 Sharp p wave L=1 Principal d wave L=2 Diffuse f wave L=3 Fine and so on.
Superconductivity: difference between s-wave and d-wave
2009年12月16日 · The standard "s-wave" is spherically symmetric (there are other s-wave symmetry that aren't, but the s-wave order parameter as used in the standard BCS model is spherically symmetric). The "d-wave" being mentioned with respect to the cuprate superconductors is the [itex]d_{x^2 - y^}[/itex] symmetry.
P-waves and S-wave reflection and refraction - Physics Forums
2008年12月4日 · Studying P-wave and S-wave reflection and refraction can provide valuable information about the Earth's interior, such as the composition and density of different layers. This can help scientists better understand plate tectonics, earthquakes, and …
S-wave and d-wave superconductivity - Physics Forums
2008年2月3日 · s-wave pairing has a isotropic energy gap. d-wave paring has nodes in the energy gap. There is a review on pairing in the cuprates in Review on Modern Physics, 72, 696 "Pairing symmetry in cuprate superconductors"
Normal incidence of EM wave - p & s polarization convention?
2018年8月24日 · The convention for determining the polarization of an EM wave is based on the direction in which the electric field oscillates. If the electric field oscillates in the direction of the y-axis, the wave is said to be p-polarized. If it oscillates in the direction of the x-axis, the wave is said to be s-polarized.
How Far Away Was the Earthquake if S Waves Arrived 2 Minutes …
2008年9月17日 · These travel at different speeds. The speed of longitudinal waves, called P waves, is 8000 m/s . Transverse waves, called S waves, travel at a slower 4500 m/s . A seismograph records the two waves from a distant earthquake. Part A If the S wave arrives 2.0 min after the P wave, how far away was the earthquake?
Wave movement and particle movement - Physics Forums
2024年3月13日 · The speed of wave movement, or wave velocity, depends on the type of wave and the medium through which it travels. For example, the speed of sound waves in air is approximately 343 meters per second, while light waves travel at approximately 299,792 kilometers per second in a vacuum.
Earthquake analysis (motion along a straight line) - Physics Forums
2007年9月10日 · I figured that the time delay will mean after the first P-wave is recorded it takes 33 seconds for the S-wave to get there, meaning the P-wave will get there in some time and then the S-wave will get there in some time + 33 seconds. So I set up: 3.5(33+t) = 6.5t t=38.5 seconds which is how long the P-wave traveled;
Calculating Distance from Earthquake Using P and S Waves
2006年11月27日 · When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 8.0 km/s and the secondary, or S, wave has a speed of about 4.5 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 88.7 s later, records the arrival of the S wave.
Reading a Seismogram, where are the S waves? - Physics Forums
2016年6月12日 · What are S waves and how are they different from P waves? S waves, or secondary waves, are a type of seismic wave that travel slower than P waves and are responsible for the side to side or transverse ground motion during an earthquake. They can only travel through solid materials, whereas P waves can travel through both solids and liquids.
