Transverse Definition and 291 Threads

Hi, So the gravitational waves detected by LIGO recently were transverse right? And this is because the weak field approximation which reduces EFE to linearized holds very well at such distances and these describe that the gravtiational waves will be transverse. I've read that you also get...

Homework Statement Alright, this problem has been driving me into a confused rage. The wave is moving in an upward direction so particle A should be moving up as well, right? But every single website I've used to study claims that it's moving in a downward direction. How? Homework...

I was reading this paper: http://dinamico2.unibg.it/recami/erasmo%20docs/SomeOld/RevisitingSLTsLNC1982.pdf It is on superluminal Lorentz transformations and is too advanced for me. :confused: But anyway, take a look at equation(s) (11). For the y' and z' transformations, there is an imaginary...

When CLAS of Jlab describe the result of the process ep→epπ,the use the terminal "transverse amplitude" Ml±(W,Q2), El±(W,Q2),and "scalar(longitudinal) amplitudes"Sl±(W,Q2),they correspond to photons of the magnetic, electric, and Coulombic type.Are they observables? The index of...

Homework Statement Why can’t transverse waves travel through a gas or liquid? Homework EquationsThe Attempt at a Solution I understand that transverse waves require rigid medium through which to transfer their energy so they can travel through solids. I'll just accept that transverse waves can...

Homework Statement A transverse pulse is propagating on a 2.0 m long string of mass 50 g. The pulse is described by the equation: y(x,t)=pi/(pi+(3x/2+pi(t))^2) , with x and y in meters, and t in seconds. Find the tension in the string. Homework Equations y=asin(wt+thetha)[/B]The Attempt at...

The Transverse resonance method is used to determine the propagation constant of a wave in several waveguides, like the rectangular waveguide, or also dielectric waveguides. It takes advantage of the fact that a standing wave is present along a certain direction (transverse with respect to the...

Hey, in sean carroll's book about GR he said something about transverse vector, can someone explain me what a transverse vector is? Also he said:"Remember that the vectors are defiend only in the two transverse dimensions" what is the meaning of transverse dimension

Let's say you know all 3 cartesian components of a particle's velocity and all 3 for it's acceleration. You can split the acceleration vector into two vectors, one parallel (longitudinal) to the velocity vector and one perpendicular (transverse) to the velocity vector. Then, I found the...

I know light is an electromagnetic wave that has an electric field and magnetic field that are perpendicular to each other. I was wondering how the oscillation was occurring? 1. Are the strength of the fields waning and waxing perpendicularly to the propogation of motion like in the case of...

Neutrinos are always left handed* and so, if you set up a coordinate system with the z-axis pointing in the direction of a neutrino's momentum, any measurement of its spin's z-component will always yield ##-\hbar/2##. What if you measured the spin of the neutrino along the x or y axes? Or is...

In deriving wave equation or power transmission of wave transmitted by a string, it is usually stated (with some assumptions) that the transverse force on a point of the string is proportional to the slope at that point. An example is given in p.20 of this notes...

Correct me if I'm wrong, but based on what I've learnt, there are three kinds of waves: mechanical, transverse progressive and longitudinal progressive. Mechanical - A disturbance makes particles vibrate on the spot Transverse progressive - Energy is carried, and moves perpendicular to the...

Homework Statement This isn't necessarily a problem, but a question I have about a certain step taken in showing that the electric and magnetic fields are transverse. In Jackson, Griffiths, and my professor's written notes, each claims the following. Considering plane wave solutions of the...

how can the electromagnetic waves be transverse and at the same time the E.M propagates in space (the definition of the transverse wave is that it is a wave in which it's medium particles propagate perpendicular to the direction of wave propagation) what i don't understand is that how can it...

I'm utterly confused by co-moving distance, transverse comoving distance and proper distance. Is comoving distance = proper distance? Then what is transverse comoving distance?

Homework Statement Hi, I encountered a problem whilst doing problems involving transverse waves. If somebody could give me a pointer I would appreciate it. The question is: "One end of a horizontal rope is attached to a prong of an electrically driven tuning fork that vibrates the rope...

The way we have a phasor analysis for a point mass executing un-damped simple SHM, is there something like that for transverse waves on a string. According to me if we fix the position then we can focus on the isolated SHM at that particular position. Is there any way in which I can relate the...

Hello everyone: This is what I read in a paper, the spontaneous emission rate written by Fermi's Golden Rule is just related to the local transverse electric field. Dose anyone can explain to me what's the meaning of "transverse mode" here? Why the emission is not related to longitudinal...

Homework Statement A transverse wave travels along x-axis . what is direction of oscillation of particles ? Homework EquationsThe Attempt at a Solution I think the answer is xy plane but Wikipedia says its yz plane . Please explain how?

I have a conceptual misunderstanding it seems. Poisson's ratio is the ratio of elastic strain deformation of the transverse and longitudinal components. That being said, if I were to induce thermal stress (heating up) to a rod by keeping its ends (longitudinal component) rigid, would there be a...

Do all standing waves have to have the same frequency and amplitude?

I am losing my mind over this, it seems the longer i think about it the further i get from a definitive answer. It started with me trying to understand the variables the would result in a standing wave, ie: what needs to occur, why, and how it occurs. At first i was confused because it seemed...

Not a specific question, but I just need help understanding how units cancel out. v = sqrt(force of tension / mass density) Force of tension is in Newtons. Mass density is in kg/m^3 Nt/ (kg/m^3) = (kg*m/s^2)/(kg/m^3) =(I cross multiply here) (kg*m*m^3)/(s^2*kg) kg cancels out...
