Waves, Sound & Light — Chapter overview · Physical Science: Matter, Forces & Energy, Grade 8
Connect vibrating sources, wave properties, sound, light and information with a complete source–medium–receiver model. This is a required chapter and is included in the course final.
Chapter question
How do waves and circuits transfer energy and information?
Units in this chapter
- Unit 8.1 · Sound Sources, Vibrations & Receivers
I can read source vibration records and distinguish amplitude, frequency and pitch.
- Unit 8.2 · Wave Properties
I can identify the amplitude, wavelength, frequency, and period of a wave.
- Unit 8.3 · Sound Waves
I can describe sound as a longitudinal (compression) wave that needs a medium to travel.
- Unit 8.4 · Light & the Electromagnetic Spectrum
I can order the electromagnetic spectrum by wavelength, frequency, and energy.
- Unit 8.5 · Waves, Information & a Speaker System
I can trace the linked electrical, magnetic, mechanical and sound mechanisms in a speaker.
