Lesson Plan
Sound Interference and Resonance
Goals / Objectives
Describe resonance in terms of natural frequency, driving force, and damping
Explain how beats arise from superposition and compute beat frequency with f_B = |f₁ − f₂|
Define fundamental, overtone, and harmonic, and explain how standing waves form in a pipe
Contrast open-pipe and closed-pipe resonators and use their resonant-frequency formulas
Solve problems involving the harmonic series and beat frequency
Standards
14.4
"The phenomenon of driving a system with a frequency equal to its natural frequency is called resonance, and a system being driven at its natural frequency is said to resonate." "Beats are produced by the superposition of two waves with slightly different frequencies but the same amplitude." "The resonant frequencies of a tube closed at one end are $f_n = n\frac{v}{4L}, , n = 1, 3, 5...$ ... The resonant frequencies of a tube open at both ends are $f_n = n\frac{v}{2L}, , n = 1, 2, 3...$"
