Upon completion of this unit, you should be able to:
- describe simple harmonic motion and describe how energy and speed vary in such motion.
- understand the equation of SHM and explain what is meant by phase and phase differences.
- describe wave motion in terms of various parameters and identify different types of waves.
- explain various wave properties and resulting phenomena.
- describe the formation and characteristics of standing waves and explain the phenomenon of resonance.
- define sound and explain the sound frequency spectrum.
- tell how the speed of sound differs in different media and describe the temperature dependence of the speed of sound in air.
- define sound intensity and explain how it varies with distance from a point source, and calculate sound intensity levels on the decibel scale.
- explain the reflection, refraction, and diffraction of sound and distinguish between constructive and destructive interference.
- describe and explain the Doppler effect and give some examples of its occurrences and applications.
- explain some of the sound characteristics of musical instruments in physical terms.
