TEACHING RESOURCES:

DEMOS
LABS
SIMULATIONS

- Transverse Waves
- Traveling Waves
- Speed of Sound Determination
- Beats and Resonance

LAB 21a. Standing Waves in a String
Objectives: To determine the experimental value of the frequency by means of a graph of collected data.
Equipment: Electric string vibrator, string, pulley with rod support, meterstick and set of masses
Type of Lab: Teacher directed

LAB 21b. Determination of the Speed of Sound
Objectives: To determine the speed of sound  in air by using resonant
air columns
Equipment: Two tuning forks of frequency greater than 400 Hz
two graduated cylinders, , water, resonant tube
Type of Lab: Open ended

LECTURE NOTES

- Waves
- Sound
- The Doppler Effect
- Interference and Diffraction
- Ripple Tank

KEY ITEMS:

• The use of simulations is particularly effective in demonstrating
  how the motion of a wave differ from the motion of particles in
  the medium.
