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.
-
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.
-
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.
-
Use a ratio to calculate how much faster one wave arrives before the other.
