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(x-v*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 One-Dimensional Wave Function
Superposition JavaScript Model shows how the superposition principle gives
rise to wave phenomena such as standing waves and beats. Users enter
real-valued 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
