Light & Sound

S8P4. Students will explore the wave nature of sound and electromagnetic radiation. a.Identify the characteristics of electromagnetic and mechanical waves. b. Describe how the behavior of light waves is manipulated causing reflection, refraction diffraction, and absorption. c. Explain how the human eye sees objects and colors in terms of wavelengths. d. Describe how the behavior of waves is affected by medium (such as air, water, solids). e. Relate the properties of sound to everyday experiences. f. Diagram the parts of the wave and explain how the parts are affected by changes in amplitude and pitch.

Why do you need to put sound proofing in a movie theater? How can small waves in the middle of the ocean become huge waves as they approach the coast? How do musical instruments make sounds of different pitch and intensity? Why do objects partially submerged in water appear broken or bent? How do we see colors? How is that we can hear someone talking with using a tin can “phone”?
