Topic 13.3: Wave motion (propagation)


Objective:
Students should understand the description of traveling waves, so they can:
  1. Sketch or identify graphs that represent traveling waves and determine the amplitude, wavelength, and frequency of a wave from such a graph.
  2. Apply the relation among wavelength, frequency, and velocity for a wave.

Objective:
a) Students should understand the difference between transverse and longitudinal waves, and be able to explain qualitatively why transverse waves can exhibit polarization.

b) Students should understand the inverse-square law, so they can calculate the intensity of waves at a given distance from a source of specified power and compare the intensities at different distances from the source.





Topic 13.4: Wave Properties


Objective:
Students should understand the principle of superposition, so they can apply it to traveling waves moving in opposite directions, and describe how a standing wave may be formed by superposition.

Objective:
Students should understand the description of traveling waves, so they can:
  1. Describe reflection of a wave from the fixed or free end of a string.
  2. Describe qualitatively what factors determine the speed of waves on a string and the speed of sound.


Topic 13.5: Standing waves & Resonance


Objective:
Students should understand the physics of standing waves, so they can:
  1. Sketch possible standing wave modes for a stretched string that is fixed at both ends, and determine the amplitude, wavelength, and frequency of such standing waves.
  2. Describe possible standing sound waves in a pipe that has either open or closed ends, and determine the wavelength and frequency of such standing waves.
