Topic 14.1 & 14.2: Sound Waves & The speed of sound


Objective:
Students should understand the description of traveling waves, so they can describe qualitatively what factors determine the speed of waves on a string and the speed of sound.

Topic 14.5: The Doppler effect


Objective:
Students should understand the description of traveling waves, so they can understand qualitatively the Doppler effect for sound in order to explain why there is a frequency shift in both the moving-source and moving-observer case.
