Transverse and longitudinal waves
Description
In this Transverse wave model, the simulation shows the phase difference
commonly associated in wave motion in terms of angle differences between
the 2 points travelling in a circular motion.
Play with the Model. Test what you've learned by exploring the phase
difference, amplitudes, wavelengths, periods, frequencies and
wave velocities.
Sample Learning Goals
(a) show an understanding and use the terms displacement, amplitude,
phase difference, period,
frequency, wavelength and speed
(f)
analyse and interpret graphical representations of transverse and
longitudinal waves
Activities
-
By changing i and j sliders, the different positions of a wave can be
simulated.
-
Determine the phase difference between the BLUE and RED point using
ϕ/(2π)
= t/T or otherwise.
-
Use the simulation to check your calculation.
-
The slider T changes the period of the wave motion, by means of
evidences from the simulation or otherwise, determine the period
-
The slider A changes the amplitude of the wave motion, by means of
evidences from the simulation or otherwise, determine the amplitude
-
the guide allows the visualization of the front view of the point BLUE
and RED.
