What was required to start each vibration, to make the system vibrate?
Which systems in your sound systems data table produced an audible sound? List all that apply.
For which systems in your sound systems data table was there a transfer of energy observed? List all that apply.
Assume that 100 paces equals 122 meters.
1. Calculate the time for the sound wave to travel from the stakes to the observers, for 100 paces. The average speed of sound is 343 m/s.
2. Calculate the time for the light wave to travel from the stakes to the observers, for 100 paces. The speed of light in air is 3 x 108 m/s.
3. Use a ratio to calculate how much faster one wave arrives before the other.
