Unit 3: Waves

Unit 3 focuses on Waves and their properties and uses. We will spend most of our time in chapter 12, with some focus on seismic waves found in chapter 28.3.

Check the Class Calendar on this website for a complete and updated list of assignments and their due dates.

CA- California K-12 Academic Content Standards
Subject : Science
Grade : Grades Nine Through Twelve
Area : Physics
Sub-Strand : Waves
Concept 4: Waves have characteristic properties that do not depend on the type of wave. As a basis for understanding this concept:
Standard a: Students know waves carry energy from one place to another.
Standard b: Students know how to identify transverse and longitudinal waves in mechanical media, such as springs and ropes, and on the earth (seismic waves).
Standard e.: Students know radio waves, light, and X-rays are different wavelength bands in the spectrum of electromagnetic waves whose speed in a vacuum is approximately 3 x 10^8 m/s (186,000 miles/second).
Standard d: Students know sound is a longitudinal wave whose speed depends on the properties of the medium in which it propagates.
Standard f: Students know how to identify the characteristic properties of waves: interference (beats), diffraction, refraction, Doppler effect, and polarization.
