Integrated Physics and Chemistry Unit 9

Big Idea:

How waves interact and apply to sound and light.

Student Expectations:

Priority TEKS

I.5G Explore the characteristics & behaviors of energy transferred by waves, including acoustic, seismic, light, & waves on water as they superpose on one another, bend around corners, reflect off surfaces, are absorbed by materials, & change direction when entering new materials.

Student Learning Targets:

I will know how waves interact.

• I can describe the parts of a wave including wavelength, amplitude, frequency, period, speed, crest, and trough.
• I can explain the difference between transverse & longitudinal waves.
• I can explain why some waves need a medium while other waves do not require a medium.
• I can use the electromagnetic spectrum to describe different forms of light.
• I can illustrate interference in waves.
• I can explain reflection, refraction, diffraction, and absorption of waves.
• I can use tuning forks or other everyday objects to explain resonance.
• I can explain polarization of light.
• I know how total internal reflection is used in fiber optics.
• I can research various electronic devices to illustrate how electromagnetic waves are used in technology.
• I can use resonance to explain how musical instruments work.
• I can use acoustic principles to explain how echolocation, sonograms, musical instruments, & noise pollution work
