Unit 14 · Waves, Sound, and Physical Optics
Chapter 14.1
Waves, Sound, and the Doppler Effect
A wave on a rope carries energy from one end to the other while every piece of rope stays home. Sound does the same through air, and a passing siren proves that motion changes what you hear.

By the end
- 01Describe waves as energy transfer without matter transfer, transverse or longitudinal, mechanical or electromagnetic
- 02Relate wave speed to the medium, and wavelength, frequency, period, and speed to one another
- 03Write a sinusoidal wave as a function of time or of position
- 04Predict qualitatively how relative motion of source and observer shifts the observed frequency
