Physics · Pedagogy and Experiments
Students stretch rubber bands of different thicknesses over a wooden box, pluck them, and measure vibration frequency using a smartphone app. This activity primarily aims to:
- 1Enable students to explore how tension, thickness, and length affect pitch through hands-on experimentation✓
- 2Determine which student can pluck the band to create the loudest amplitude
- 3Replace textbook-based explanations of acoustics and wave theory entirely
- 4Test the accuracy limits of standard smartphone microphones
Correct answer
Enable students to explore how tension, thickness, and length affect pitch through hands-on experimentation
