This module contains 13 lessons that provide a rich combination of hands-on investigations and interactive simulations for learning about harmonic motion (oscillations), waves, and sound. You will investigate properties of amplitude, period, frequency, wavelength, and wave speed, and distinguish between transverse and longitudinal waveforms. Interactive elements, such as the ripple tank simulation, allow you to explore wave behaviors such as reflection, refraction, diffraction, absorption, interference, and resonance, as well as the phenomena of standing waves. Sound waves are represented with several different types of graphs and charts, including waveform graphs, frequency spectrum graphs, and spectrogram charts. You will use interactive simulations to experiment with these representations and with the phenomena of beats and the Doppler effect. The module concludes with a project for designing a musical instrument.
Also needed for two investigations:
Physics of Sound is an application used in four
of the investigations, and it requires installation. Instructions are provided below.
