Waves
Dear Parent and Student,
Your son’s or daughter’s science class will soon begin exploring the chapter entitled “The Energy of Waves.” In this chapter, students will learn about waves and how they affect everyday life. By the end of the chapter, students should demonstrate a clear understanding of the chapter’s main ideas and be able to discuss the following topics:
1 how waves transfer energy without transferring matter (Section 1)
2 explain and give examples of waves that require a medium and waves that do not (Section 1)
3 the difference between transverse and longitudinal waves (Section 1)
4 amplitude, wavelength, frequency, and wave speed (Section 2)
5 how amplitude and frequency are related to the energy of a wave (Section 2)
6 reflection, refraction, diffraction, and interference (Section 3)
7 the difference between destructive interference and constructive interference (Section 3)
8 the phenomenon of resonance and some examples (Section 3)
The Internet at Home
If you have Internet service at home, you and your child can access information related to the chapter entitled “The Energy of Waves.” The following resources are available for your use.
sciLINKS: At www.scilinks.org you will find links to Web sites that have been selected by the staff at the National Science Teachers Association (NSTA). The staff at NSTA regularly scans the Internet to find sites that are current, engaging, and appropriate for middle school students. Check out the latest links by typing in the sciLINKS numbers listed below.
