2013年4月21日 · Homework Statement How do you find wavelength given this wave graph? [ignore my title please]Homework Equations c= (wavelength)(frequency)The Attempt at a Solution I always see displacement (y) vs distance (x) graph, but this one is displacement (x) vs t I'm kinda confused how you solve...

2011年3月29日 · The graph is at a single location. The wave velocity is 12m/s., so in a time of 10 seconds, a wave travels 120 meters. The graph tells you that 4 waves pass by in a time of 10 seconds. Put those together, and 4 waves span a distance of 120 meters.

2016年3月16日 · With a wave like ##y=A\sin kx## you can see that the displacement (y) varies with distance (x) from some origin, but it does not vary with time. The the displacement-distance graph would be a sine wave, while the displacement …

2009年3月4日 · I have a question asking for the period, frequency, amplitude and phase angle from simply looking at a graph. I have the period and frequency, and 'think' i have the amplitude (high point - low point / 2), but I don't know how to get the phase angle. No equation is given so I can't simply consider the coefficients in front of sin and cos.

2006年8月26日 · The solution for a traveling wave is: [tex]y(x,t) = Asin(\frac{2\pi}{\lambda}x - \omega t)[/tex] To turn it into a displacement distance graph, just plot y as a function of x, keeping t constant.

2017年2月1日 · Also I know that the history graph shows what is happening to the medium at the specific point. But when it comes to graphs that are a bit more complex than easier x positions and different velocities I lose track of what's going on. With this problem it says it is a history graph at x=2m with the wave moving at 3 m/s.

2016年10月25日 · The wave function need not be a pure sinusoid, but instead a solution to Schrodinger equation for the system in question which may be exponentials e.g. a free particle with energy higher than a constant potential or sinusoids (a free particle with energy lower than a constant potential) or a Hermite polynomial multiplied by Gaussian exponentials (a harmonic …

2014年3月12日 · The figure shows the displacement y of a traveling wave at a given position as a function of time and the displacement of the same wave at a given time as a function of position. How fast is the wave traveling? View attachment 67578 The Attempt at a Solution I'm totally lost with this question. How should I approach this? v = λ/ T

2011年1月16日 · Homework Statement A triangular wave is produced by the following combination of harmonics Using Microsoft© Excel, synthesise a triangular wave. Start with a plot of the first term and gradually add the next term. Print …

2008年5月9日 · Draw the history graph D(x=0m, t) at x= 0m for the wave shown in the figure. Homework Equations The Attempt at a Solution I'm not quite understanding the concept of snapshot and history graphs. I think for this one the problem is that is is moving left. The graph that I drew is the wrong one.
