  1. Lab 8 Hints

  2. Activity3: Clapping hand near open tube • These slides indicate how to set up LoggerPro to “trigger” when you clap your hand.

  3. You may wish to have the computer capture sounds automatically when a loud enough sound is produced. This is called “triggering” • First, zero the probe • Under menu Experiment, select Zero when the room is quiet. • This sets the pressure reading to zero when there is no sound present.

  4. Select the clock icon near the Collect button. This opens the triggering menu Triggering menu

  5. Select the Triggering tab

  6. Indicate the pressure amplitude at which you want the computer to trigger. Too low and you trigger on noise. Too high and it will not capture your sound.

  7. Click Done when you are finished. Now when you press the Collect button, the computer will wait until it detects a sound with the pressure level you indicated.

  8. Activity5: speed of sound in air column Hold tuning vibrating tuning fork above tube. Listen for resonance and you slowly raise water level. Tube Water reservoir

  9. When you find a resonance, mark the water level with a piece of tape. Masking tape
