CLASS ACTIVITY: TUNING FORK FREQUENCY

Class Activity: Class Activity: Tuning Fork FrequencyTuning 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

Data: Sound DetectorsData: Sound Detectors1. Generate and

capture the wave pattern created by each tuning fork.

2. Determine f
