Description
Play with the 2 Wave Superposition Model. Test what you've learned by exploring the amplitudes, wave velocities, frequencies, wavelengths.
As a pedagogical tool, "modeling pedagogy: key in your own equation like A*sin(2*pi/λ(xv*t) form" .
for ease of keying in, select from the dropdown menu is also possible before adding on through the input fields of f(x) and g(x).
The OneDimensional Wave Function Superposition JavaScript Model shows how the superposition principle gives rise to wave phenomena such as standing waves and beats. Users enter realvalued wave functions and observe both the time dependent functions and their superposition. This model uses the JavaScript mathematical function parser.
Sample Learning Goals
(a) show an understanding and use the terms displacement, amplitude, phase difference, period,frequency, wavelength and speed
(b) deduce, from the definitions of speed, frequency and wavelength, the equation v = fλ
(c) recall and use the equation v = fλ
(f) analyse and interpret graphical representations of transverse and longitudinal waves
(a) explain and use the principle of superposition in simple applications
