Apr 22, 2013 · Yes, you can find frequency from a wave graph with irregular waves by measuring the time it takes for a single wave to pass a fixed point and then calculating the frequency using the formula f = 1/T. However, this method may not be as accurate as finding the frequency from a graph with regular waves.

Feb 29, 2016 · 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-time graph (for each value of x) is a horizontal line.

Aug 26, 2006 · 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.

Mar 4, 2009 · 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.

Mar 29, 2011 · 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.

Feb 4, 2013 · However, the frequency of the wave affects the number of cycles or repetitions of the wave per unit time, which can change the shape of the wave on the y axis. Similar threads I Equation to graph a sine wave that acts like a point on a unit circle

Mar 12, 2014 · To find the wave's speed, use the equation v = λ/T where λ is the wavelength and T is the period of the wave. By analyzing the two graphs provided, you can determine the wavelength and period, which can then be used to calculate the wave's speed. In this case, the wave's speed is 0.75 meters per second.

Feb 1, 2017 · 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.

Oct 25, 2016 · 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 …
