Longitudinal Definition and 129 Threads

Homework Statement a longitudinal wave in a 6.0m long spring has a frequency of 10.0 Hz and a wavelength of 0.75m. calculate the speed of the wave and the time that it would take to travel the length of the spring. Homework Equations v = f (wavelength) The Attempt at a Solution v =...

hey friends please solve my problem Both longitudinal and transverse waves can propagate through a solid. A wave on the surface of a liquid can involve both longitudinal and transverse motion of elements of the medium. On the other hand, a wave propagating through the volume of a fluid must be...

Homework Statement A vet is using an ultrasonic motion detector to detect the heartbeat of an unborn chimp baby and claims that the speed of sound in the soft tissue of a chimp should be 1489 m/s. According to the manual which comes with the motion detector, the emitted frequency of sound...

Homework Statement Please explain the difference and try to give examples. I know that the displacement of the medium in a transverse wave is perpendicular to the direction of wave travel and in longitudinal is parallel to the direction of wave travel, but does this mean that transverse waves...

I want to be able to differentiate between longitudinal(P) and Shear(S) waves in solids. Using one Acoustic emission (AE) senor placed 2 to 20 cm form a AE source e.g. a stress induced crack or pencil lead test, how can one detect both the P and S waves and determine what part of the receive...

Why is it that when a longitudinal wave is represented by a (pressure/position) and a (displacement/position) graph does the displacement 0 represent a compression or rarefaction (maximum or minimum pressure)?

Homework Statement Show that all longitudinal waves must be electrostatic by using Faraday's law. Homework Equations Faraday's law: \frac{\partial \vec{B}}{\partial t} = - \nabla \times \vec{E} The Attempt at a Solution Where should I start??

seeking help..please why do low frequency contributes a low pitch?how?& why only longitudinal in fluids?can any1 please explain to me,tq please..:smile:

Hi everybody, In chapter 10 of Kittel's "Introduction to Solid State Physics" it is said that the zeros of the dielectric functions determine the frequency of the longitudinal modes of oscillation, \epsilon(\omega_L) = 0, Eq. (17). Am I missing something or this is actually an "unproved claim"...

I know that when a Longitudinal (Sound) Wave spreads in water the displacement of the water particles is parallel to the direction of wave propagation and the displacement equation looks like this : y(x,t)=A*sin[2*π*f*(t-x/u)] where : A=Amplitude, π=3.14..., f=frequency, u=speed of...

Hi guys, this is Barton Zwiebach's Introduction to String theory question 4.2 on the longitudinal wave on a taut string. The problem is purely classical and I seem to obtain a solution which seems far too complicated for me. If anyone has the answers it would be great, if not just your help...

Why can’t longitudinal waves be polarized? I’m guessing its something to do with the particles oscillating in the same direction of propagation, but I can’t think of a explanation of why they can’t be polarized. I have also been told that some transverse waves can’t be polarized. X-rays can...

Pretty basic question, i think, it's either possible or it's not. Physics practical using an ultrasound generator and receiver components (in separate circuits, with the the generator rigged up to signal generator, and the receiver connected to an oscilloscope to take readings from). For the...

So we are working on sound waves in my physics course now and I was doing some textbook reading. I have been following it pretty well, but I just came across a relationship that I am not quite following. It is with reference to wave interference. Let us say that two sound waves are emitted...

wat will be the longitudinal static stability of an aircraft with a larger wing to a smaller wing?

"Calculate the initial diameter of a wire that has been longitudinally strained by 30% and whose final diameter is 0.1cm. Assume no volume change." Now I know that if there is no volume change, v=poisson's ratio= 0.5. Thus the lateral strain would equal 30%*0.5= 15%. But when I plug it...

Hi guys: Why people consider the plasmon ocsilation as a longitudinal wave? Thank you for your answer. sinayu

Hi. I am hoping someone can be of assistance in helping me solve a problem. I am trying to calculate the longitudinal elongation of the steel bar shown in the attachment. I don't know where to start, so if anyone could point me in the right direction such as which formula I should use I would...

Sound is just Longitudinal vibrations of air that are detected from objects like the ear. Hence it originates from a vibrator. For humans this vibrator is in the neck in the form of a vocal cord. So sound from humans really comes from the neck and the vibrations of air ascend up the neck and...

transverse longitudinal waves : slinky lab! so this lab we did is called the transmission and reflection of a one-dimensional transverse wave... 1. we created a transverse pulse from one side and observed a point near the middle of the spring as the pulse passed... - > so i wrote that it just...

Sir, It is said that it is possible to distinguish between transverse and longitudinal waves by studying the property of polarization. Also it is said that longitudinal waves cannot be polarized but transverse waves can be polarized. Are they true?

Am I right to assume that a tall, thin, and rigid rod will likely fail under transverse loading (that is, perpendicular to its length) ? Similarly, would a tall, thin, and rigid rod do well under longitudinal stress?

hello im just confusing about the electrical conduction in the electrical circuits I mean, for example, -an alternate voltage means that the electrons move back and forth in the circuit? -if really this happens, then the electric waves in the circuit are LONGITUDINAL, because by definition...

Hello! Okay, here we go. Q1. A block is resting on top of a flat plate that is oscillating vertically with simple harmonic motion. If the frequency of the plate's oscillation is 2.0 Hz, what is the maximum amplitude it can have before the block loses contact with the plate? - This...

i've found 2 equations on longitudinal velocity of waves v=lambda*freq and v=Lsqrt(k/m). is the 2nd equation derived from the 1st? if not how do you derive it? thx.

I'm confused by something my book says. For reference, here is the relevant text: Figure 18-5b shows an oscillating element of air of cross-sectional area A and thickness \Delta x, with its center displaced from its equilibrium position by a distance s. From Eq. 18-2 we can write, for the...

what is meant by SINGLE LONGITUDINAL MODE in laser?

I don't recall what thread it was in but there was a comment that F = ma for a relativistic mass. I stated it was incorrect but did not provide a proof since it was a bit involved and too mathy for latex so instead of doing the latex out I made a new web page. For the derivation of the correct...
