- Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
- Guided Notes →One page your students fill in and keep.
- Exit Ticket →Three items at the end of class. No student accounts.
- Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
- Homework →Assign practice; it grades itself.
"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 $f_n = n\frac{v}{2L}, \, n = 1, 2, 3...$"

What you'll learn
- 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
