Vibrations, Waves and Sound Unit

Chapters 25 & 26

Study Guidelines/ What is to be accomplished?

Describe the period of a pendulum.
Describe the characteristics and properties of waves.
Describe wave motion.
Describe factors that affect the speed of a wave.
Distinguish between transverse waves and longitudinal waves.
Distinguish between constructive and destructive interference.
Describe how a standing wave occurs.
Describe the Doppler effect for sound and relate it to the blue and red shifts for light.
Describe bow waves.
Describe sonic booms.

11. Relate the pitch of a sound to its frequency.

12. Describe the movement of sound through air.

13. Compare the transmission of sound through air with that through solids, liquids, and a vacuum.

14. Describe factors that affect the speed of sound.

15. Describe loudness and sound intensity.

16. Give examples of forced vibration.

17. Describe natural frequency.

18. Describe resonance.

19. Describe how sound waves interfere with one another.

20. Describe beats.

State Standards and Benchmarks Addressed by this unit:

P.1.22 – Describe waves in terms of their fundamental characteristics of velocity, wavelength, frequency or period, and amplitude. Know that radio waves, light, and X-rays are different wavelength bands in the spectrum of electromagnetic waves, whose speed in a vacuum is approximately 3x10⁸ m/s (186,000 miles/s).

P.1.23 – Use the principle of superposition to describe the interference effects arising from propagation of several waves through the same medium.
