1. PHYSICS CLASS ACTIVITY

2. CLASS ACTIVITY: TUNING FORK FREQUENCY

3. Class Activity: Tuning Fork Frequency Goal: –To measure the frequency generated by 5 different tuning forks. Sound detectors will be utilized to determine f –Compare the measured frequency to the rated frequency. –Calculate the of the sound waves created

4. Data: Sound Detectors 1.Generate and capture the wave pattern created by each tuning fork. 2.Determine f

5. Sample Data 5 waves t = 10 ms =.01s f = # cycles time = 5 cycles.01 s = 500 Hz

6. Class Activity: Tuning Fork Frequency f rated # cycles t (s)f measured  (m) 1 2 3 4 v = 340m/s
